Interpreting F Test Results. Ask Question Asked 7 years 9 months ago. Notice however that the F-Test is sensible to non-normality and other tests are more suitable in this case see the Levene-Test or Brown-Forsyth Test for more robust. If you know what the null and alternative hypotheses are then you know how to interpret that test. First we manually calculate F statistics and critical values then use the built-in test command.
Set in parentheses Uppercase for F. So far I have run various tests to check whether I should use a fixed or random effects model as well as tests to check for autocorrelation and heteroskedasticity as well as an F-test. With this test we get an idea of the shape and size of red blood cells. This is a special case of wald_test that always uses the F distribution. A tutorial on how to conduct and interpret F tests in Stata. Interpretation of the result.
Click in the Variable 1 Range box and select the range A2A7.
Select F-Test Two-Sample for Variances and click OK. In this case width refers to a measurement of distribution not the size of the cells. First we manually calculate F statistics and critical values then use the built-in test command. If the probability of the F value ie Sig. An r x k array where r is the number of restrictions to test and k is the number of regressors. Be sure that the variance of Variable 1 is higher than the variance of Variable 2.
