I generally use anova() for GLM comparison. When applied to an lm or aov object, it displays separate effects (SS) for each term in the model and doesn't show TSS. (I used to apply … WebPaul F.M. Krabbe, in The Measurement of Health and Health Status, 2024 Abstract. Classical test theory is a body of related theory that can help us to understand and improve the reliability of measurement instruments. To reach a sufficient level of reliability, multiple items that are assumed to tap into the same underlying health aspect are scored and the …

An F-test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. 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" … See more Common examples of the use of F-tests include the study of the following cases: • The hypothesis that the means of a given set of normally distributed populations, all having the same standard deviation, are equal.
