WebThe Chi-square test statistic is calculated as follows: χ 2 ∗ = ∑ i = 1 r c ( O i − E i) 2 E i. Under the null hypothesis and certain conditions (discussed below), the test statistic … WebThe Chi-square test statistic is calculated as follows: χ 2 ∗ = ∑ i = 1 r c ( O i − E i) 2 E i. Under the null hypothesis and certain conditions (discussed below), the test statistic follows a Chi-square distribution with degrees of freedom equal to ( r − 1) ( c − 1), where r is the number of rows and c is the number of columns.

The p -value is the combined area in both tails. An alternative way to calculate the p -value (p) given by LinRegTTest is the command 2*tcdf(abs(t),10^99, n-2) in 2nd DISTR.
In statistics, Cochran's C test, named after William G. Cochran, is a one-sided upper limit variance outlier test. The C test is used to decide if a single estimate of a variance (or a standard deviation) is significantly larger than a group of variances (or standard deviations) with which the single estimate is supposed … See more The C test detects one exceptionally large variance value at a time. The corresponding data series is then omitted from the full data set. According to ISO standard 5725 the C test may be iterated until no further … See more • Bartlett's test • Levene's test • Brown–Forsythe test • Hartley's test • F-test of equality of variances See more The sample variance of data series j is considered an outlier at significance level α if Cj exceeds the upper limit critical value CUL. CUL depends on the desired significance level α, … See more The C test can be generalized to include unbalanced designs, one-sided lower limit tests and two-sided tests at any significance level α, for any number of data series N, and for any number of individual data points nj in data series j.
