Fmax statistic
WebThe F-statistic is the test statistic for F-tests. In general, an F-statistic is a ratio of two quantities that are expected to be roughly equal under the null hypothesis, which produces an F-statistic of approximately 1. The F-statistic incorporates both measures of variability discussed above. In statistics, Hartley's test, also known as the Fmax test or Hartley's Fmax, is used in the analysis of variance to verify that different groups have a similar variance, an assumption needed for other statistical tests. It was developed by H. O. Hartley, who published it in 1950. The test involves computing the ratio of the largest group variance, max(sj ) to the smallest group variance, min(sj ). The resulting ratio, Fmax, is then compared to a critical value from a table of t…
