In statistics , Mood s median test is a special case of Pearson s chi squared test . It is a nonparametric test that tests the null hypothesis that the median s of the Statistical population population s from which two Sampling statistics samples are drawn are identical. The data in each sample are assigned to two groups, one consisting of data whose values are higher than the median value in the two groups combined, and the other consisting of data whose values are at the median or below. A Pearson s chi squared test is then used to determine whether the observed frequencies in each group differ from expected frequencies derived from a Frequency distribution distribution combining the two groups. The test has low Statistical power power efficiency for moderate to large sample sizes, and is largely regarded as obsolete. The Wilcoxon&ndash Mann&ndash Whitney U two sample test should be considered instead. Siegel & Castellan 1988, p. 124 suggest that there is no alternative to the median test when one or more observations are off the scale. The relevant difference between the two tests is that the median test only considers the position of each observation relative to the overall median, whereas the Wilcoxon&ndash Mann&ndash Whitney test takes the ranks of each observation into account. Thus the latter test is usually the more powerful of the two. Spoken Wikipedia Median test.ogg 2006 01 20 See also Sign test a paired alternative to the median test.

In mathematics , the n th term test for divergence ref name Kaczor Kaczor p.336 ref is a simple test for the divergent series divergence of an infinite series If math lim n to infty a n neq 0 math or if the limit does not exist, then math sum n 1 infty a n math diverges. Many authors do not name this test or give it a shorter name. ref name Rudin For example, Rudin p.60 states only the contrapositive form and does not name it. Brabenec p.156 calls it just the nth term test . Stewart p.709 calls it the Test for Divergence . ref Usage Unlike stronger convergence tests , the term test cannot prove by itself that a series convergent series converges . In particular, the converse to the test is not true instead all one can say is If math lim n to infty a n 0, math then math sum n 1 infty a n math may or may not converge. In other words, if math lim n to infty a n 0, math , the test is inconclusive. The Harmonic series mathematics harmonic series is a classic example of a divergent series whose terms limit to zero. ref Rudin p.60 ref The more general class of Harmonic series mathematics p series , math sum n 1 infty frac 1 n p , math exemplifies the possible results of the test If p 0, then the term test identifies the series as divergent. If 0 p 1, then the term test is inconclusive, but the series is divergent by the integral test for convergence . If 1 p , then the term test is inconclusive, but the series is convergent, again by the integral test for convergence.

Expert subject statistics date March 2011 In statistics , Barnard s test is an exact test of the null hypothesis of independence of rows and columns in a contingency table . It is an alternative to Fisher s exact test but is more time consuming to compute. The test was first published by George Alfred Barnard 1945, 1947 who claimed this test for 2× 2 contingency tables is more statistical power powerful than Fisher s exact test . Mehta and Senchaudhuri 2003 explain why Barnard s test can be more powerful than Fisher s under certain conditions. blockquote When comparing Fisher s and Barnard s exact tests, the loss of power due to the greater discreteness of the Fisher statistic is somewhat offset by the requirement that Barnard s exact test must maximize over all possible p values , by choice of the nuisance parameter . For 2 2 tables the loss of power due to the discreteness dominates over the loss of power due to the maximization, resulting in greater power for Barnard s exact test. But as the number of rows and columns of the observed table increase, the maximizing factor will tend to dominate, and Fisher s exact test will achieve greater power than Barnard s. blockquote Mato and Andres 1997 show how to compute the result of the test more quickly.

In statistics , Bartlett s test George W. Snedecor Snedecor and William Gemmell Cochran Cochran , 1983 is used to test if k samples are from populations with equal variance s. Equal variances across samples is called homoscedasticity or homogeneity of variances. Some statistical tests, for example the analysis of variance , assume that variances are equal across groups or samples. The Bartlett test can be used to verify that assumption. Bartlett s test is sensitive to departures from normality. That is, if the samples come from non normal distributions, then Bartlett s test may simply be testing for non normality. Levene s test and the Brown Forsythe test are alternatives to the Bartlett test that are less sensitive to departures from normality. Citation needed date February 2012 The test is named for M. S. Bartlett Maurice Stevenson Bartlett . Specification Bartlett s test is used to test the null hypothesis, H sub 0 sub that all k population variances are equal against the alternative that at least two are different. If there are k samples with size math n i math and sample variance s math S i 2 math then Bartlett s test statistic is math X 2 frac N k ln S p 2 sum i 1 k n i 1 ln S i 2 1 frac 1 3 k 1 left sum i 1 k frac 1 n i 1 frac 1 N k right math where math N sum i 1 k n i math and math S p 2 frac 1 N k sum i n i 1 S i 2 math is the pooled estimate for the variance. The test statistic has approximately a math chi 2 k 1 math distribution. Thus the null hypothesis is rejected if math X 2 chi 2 k 1, alpha math where math chi 2 k 1, alpha math is the upper tail critical value for the math chi 2 k 1 math distribution .

notability date April 2012 In statistics , the Johansen test ref Johansen, S ren, Estimation and Hypothesis Testing of Cointegration Vectors in Gaussian Vector Autoregressive Models , Econometrica, Vol.59, No.6 Nov 1991 1551&ndash 1580. jstor 2938278 ref , named after S ren Johansen, is a procedure for testing cointegration of several Order of integration I 1 time series . This test permits more than one cointegrating relationship so is more generally applicable than the Engle Granger test which is based on the Dickey&ndash Fuller test Dickey&ndash Fuller or the Augmented Dickey&ndash Fuller test augmented test for unit root s in the residuals from a single estimated cointegrating relationship. There are two types of Johansen test, either with trace or with eigenvalue , and the inferences might be a little bit different. The null hypothesis for the trace test is the number of cointegration vectors r ?, the null hypothesis for the eigenvalue test is r ?. Just like a unit root test , there can be a constant term, a trend term, both, or neither in the model. For a general Vector autoregression VAR p model math X t mu Phi D t Pi p X t p cdots Pi 1 X t 1 e t , quad t 1, dots,T math There are two possible specifications for error correction that is, two VECM vector error correction model s 1.
