F test significance
WebF-test for testing significance of regression is used to test the significance of the regression model. The appropriateness of the multiple regression model as a whole can be tested by this test. A significant F value indicates a linear relationship between Y and at least one of the Xs. Assumptions WebThe F test may be performed by comparing the F statistic (computed from your data) to the critical F value from the F table as shown in Table 15.2.6.The result is significant if the F statistic is larger because this indicates greater differences among the sample averages. Remember that, as is usually the case with hypothesis testing, when you accept the null …

It is most often used when comparing statistical models that have been fitted to a data set, in order to identify the model that best fits the population from which the data were sampled. Exact "F-tests" mainly arise when the models have been fitted to the data using least squares. The name was coined by George W. Snedecor, in honour of Ronald Fisher. Fisher initially developed the statisti…
