WebIf the null hypothesis is correct, then the F statistic will be small (if the group means are all identical, it will be 0). When the group means start to differ, the F statistic gets larger. Hence, only large values make us think the null hypothesis is wrong, and thus we only look at the right tail. ( 4 votes) Alexander Percy 7 years ago http://www.biostathandbook.com/fishers.html

In statistics, Fisher's method, also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses). It was developed by and named for Ronald Fisher. In its basic form, it is used to combine the results from several independence tests bearing upon the same overall hypothesis (H0).

WebIt is commonly stated that the degrees of freedom for the chi-square distribution of the statistic are then k − 1 − r, where r is the number of unknown paraméters. This result is valid when the original data was multinomial and hence the estimated paraméters are efficient for minimizing the chi-square statistic. http://jse.amstat.org/v19n2/doane.pdf

WebTherefore, the Factorization Theorem tells us that Y = X ¯ is a sufficient statistic for μ. Now, Y = X ¯ 3 is also sufficient for μ, because if we are given the value of X ¯ 3, we can easily get the value of X ¯ through the one-to-one function w = y 1 / 3. That is: W = ( X ¯ 3) 1 / 3 = X ¯. On the other hand, Y = X ¯ 2 is not a ... WebThe F distribution has a natural relationship with the chi-square distribution.
