Abstract:
Despite its common practice, statistical hypothesis testing presents challenges in interpretation. For instance, in the standard frequentist framework there is no control of the type II error. As a result, the non-rejection of the null hypothesis $(H_{0})$ cannot reasonably be interpreted as its acceptance. We propose that this dilemma can be overcome by using agnostic hypothesis tests, since they can control the type I and II errors simultaneously. In order to make this idea operational, we show how to obtain agnostic hypothesis in typical models. For instance, we show how to build (unbiased) uniformly most powerful agnostic tests and how to obtain agnostic tests from standard p-values. Also, we present conditions such that the above tests can be made logically coherent. Finally, we present examples of consistent agnostic hypothesis tests.

Abstract:
In a mathematical approach to hypothesis tests, we start with a clearly defined set of hypotheses and choose the test with the best properties for those hypotheses. In practice, we often start with less precise hypotheses. For example, often a researcher wants to know which of two groups generally has the larger responses, and either a t-test or a Wilcoxon-Mann-Whitney (WMW) test could be acceptable. Although both t-tests and WMW tests are usually associated with quite different hypotheses, the decision rule and p-value from either test could be associated with many different sets of assumptions, which we call perspectives. It is useful to have many of the different perspectives to which a decision rule may be applied collected in one place, since each perspective allows a different interpretation of the associated p-value. Here we collect many such perspectives for the two-sample t-test, the WMW test and other related tests. We discuss validity and consistency under each perspective and discuss recommendations between the tests in light of these many different perspectives. Finally, we briefly discuss a decision rule for testing genetic neutrality where knowledge of the many perspectives is vital to the proper interpretation of the decision rule.

Abstract:
We propose a new class of unit root tests that exploits invariance properties in the Locally Asymptotically Brownian Functional limit experiment associated to the unit root model. The invariance structures naturally suggest tests that are based on the ranks of the increments of the observations, their average and an assumed reference density for the innovations. The tests are semiparametric in the sense that they are valid, that is, have the correct (asymptotic) size, irrespective of the true innovation density. For a correctly specified reference density, our test is point-optimal and nearly efficient. For arbitrary reference densities, we establish a Chernoff–Savage-type result, that is, our test performs as well as commonly used tests under Gaussian innovations but has improved power under other, for example, fat-tailed or skewed, innovation distributions. To avoid nonparametric estimation, we propose a simplified version of our test that exhibits the same asymptotic properties, except for the Chernoff–Savage result that we are only able to demonstrate by means of simulations.

Abstract:
Understanding the role of vegetation fires in the Earth system is an important environmental problem. Although fire occurrence is influenced by natural factors, human activity related to land use and management has altered the temporal patterns of fire in several regions of the world. Hence, for a better insight into fires regimes it is of special interest to analyze where human activity has altered fire seasonality. For doing so, multimodality tests are a useful tool for determining the number of annual fire peaks. The periodicity of fires and their complex distributional features motivate the use of nonparametric circular statistics. The unsatisfactory performance of previous circular nonparametric proposals for testing multimodality justifies the introduction of a new approach, considering an adapted version of the excess mass statistic, jointly with a bootstrap calibration algorithm. A systematic application of the test on the Russia–Kazakhstan area is presented in order to determine how many fire peaks can be identified in this region. A False Discovery Rate correction, accounting for the spatial dependence of the data, is also required.

Abstract:
Circular and spherical data arise in many applications, especially in biology, Earth sciences and astronomy. In dealing with such data, one of the preliminary steps before any further inference, is to test if such data is isotropic, that is, uniformly distributed around the circle or the sphere. In view of its importance, there is a considerable literature on the topic. In the present work, we provide new tests of uniformity on the circle based on original asymptotic results. Our tests are motivated by the shape of locally and asymptotically maximin tests of uniformity against generalized von Mises distributions. We show that they are uniformly consistent. Empirical power comparisons with several competing procedures are presented via simulations. The new tests detect particularly well multimodal alternatives such as mixtures of von Mises distributions. A practically-oriented combination of the new tests with already existing Sobolev tests is proposed. An extension to testing uniformity on the sphere, along with some simulations, is included. The procedures are illustrated on a real dataset.

The German soccer league reported 10 positive tests for the coronavirus among 36 clubs in the Bundesliga and second division on Monday.

CNA Staff, May 8, 2020 / 12:30 pm (CNA).- A federal judge in Arkansas on Thursday upheld the state’s requirement that women obtain a negative coronavirus test before having an abortion.

Calling the decision “agonizingly difficult,” Judge Brian Miller for the Eastern District Court of Arkansas said the state’s testing mandate—which applies to all elective surgeries and not just abortions—is “reasonable” during the public health emergency and was not done “with an eye toward limiting abortions.

The judge noted that “it is undisputed that surgical abortions have still taken place.”

The abortion clinic Little Rock Family Planning Services had requested a temporary injunction on the state health department’s requirement that elective surgery patients obtain a negative new coronavirus (COVID-19) test result within 48 hours before the procedure.

Previously, the health department ordered a halt to non-essential surgeries on April 3 to preserve resources for treating COVID-19.

The Little Rock abortion clinic performed abortions while claiming they were offering “essential” procedures, and after the health department ordered them to stop on April 10, the clinic challenged the state in court. The diocese’s Respect Life Office noted that women were traveling to the clinic for abortions from nearby states such as Texas and Louisiana.

The clinic won its case for a temporary restraining order at the district court level, but the Eighth Circuit appeals court subsequently overruled that decision and sided with the state.

The April 3 directive was updated April 24 to allow for some elective surgeries provided certain conditions were met. Elective abortions were included in the “non-essential” surgeries that were allowed to continue on April 24.

These conditions included no overnight stays, no contact with COVID-19 patients in the previous 14 days, and a negative COVID-19 test for patients within 48 hours of the surgery.

According to the clinic, which asked for a temporary injunction, three women were seeking to obtain “dilation and evacuation” abortions but were prevented from meeting the state’s testing requirmenet. One woman said she was unable to get a COVID-19 test; another said the lab could not guarantee she would receive results in 48 hours. The third woman was unable to get an abortion in Texas, and drove to the Little Rock clinic; she was told the results of her test would not be available for several days.

In response, the state’s health department said that four surgical abortions had still been performed at the clinic between April 27 and May 1, with COVID-19 test results having been obtained within 48 hours of the abortions, and thus the directive was not an “undue burden” on women seeking abortion.

In his decision on Thursday, Judge Miller said that the pandemic is a serious threat, noting that at the time of the opinion more than 70,000 people had died in the U.S. from the virus including more than 3,500 people in Arkansas.

He said the case “presents the tug-of-war between individual liberty and the state’s police power to protect the public during the existing, grave health crisis,” and noted that the three women as well as others “are very troubled. There is a strong urge to rule for them because they are extremely sympathetic figures, but that would be unjust.”

Vatican City, Mar 31, 2020 / 10:28 am (CNA).- Cardinal Philippe Ouédraogo of Burkina Faso has tested positive for the coronavirus, his archdiocese announced Tuesday. He is the second cardinal known to have tested positive for the virus, which is now a global pandemic.

Ouédraogo, 75, has been admitted to a medical clinic in Burkina Faso’s capital Ouagadougou.  He is “in good condition and his close collaborators are reported to be self-isolating,” a spokesman for Burkina Faso’s bishops’ conference, Fr. Paul Dah, told ACI Africa on March 31.

The cardinal is president of the African continental bishops’ conference, the Symposium of Episcopal Conferences of Africa and Madagascar (SECAM). He was elected to the post in July 2019. He has been Archbishop of Ouagadougou in Burkina Faso for ten years, and was made a cardinal by Pope Francis in 2014.

Ouédraogo is the second bishop from Burkina Faso known to have contracted COVID-19, as countries across Africa implement lockdowns and restrictions to slow the spread of the virus across the continent.

Another Burkina Faso bishop, Archbishop Emeritus Séraphin François Rouamba of Koupela, tested positive for COVID-19 after being admitted to Our Lady of Peace clinic for urgent treatment on March 19.

The 78-year-old archbishop has since been transferred to another hospital and is reportedly in stable condition, according to a March 25 statement from Bishop Laurent Birfuore Dabire of Dori, Burkina Faso.

Burkina Faso has the largest documented coronavirus outbreak in West Africa, with 249 documented cases as of March 31, according to Johns Hopkins University Coronavirus Resource Center.

The coronavirus has spread throughout the African continent to 47 countries, according to the Africa Center for Disease Control. In North Africa, Egypt, Algeria, and Morocco each have more than 500 documented cases, and the South African government has reported more than 1,300.

Three Nigerian states began two-week mandatory lockdown this week to combat the spread of the virus, including Lagos, Africa’s most populous city with more than 20 million people.

Zimbabwe and Mauritius have also implemented national shut-downs, and the bishops in South Sudan and Zimbabwe have suspended public Masses.

Cardinal Angelo De Donatis, vicar general of the Diocese of Rome, tested positive for coronavirus on March 30.

Other bishops in Italy, France, China, and the United States have also tested positive for COVID-19, and Bishop Angelo Moreschi, 67, died in the Italian city of Brescia on March 25 after contracting the coronavirus.
