WebIn the linear regression model, the coefficient of determination, R 2, summarizes the proportion of variance in the dependent variable associated with the predictor (independent) variables, with larger R 2 values indicating that more of the variation is explained by the model, to a maximum of 1. For regression models with a categorical dependent variable, … WebMay 12, 2024 · What you need to know. Interpreting the result of a test for covid-19 depends on two things: the accuracy of the test, and the pre-test probability or estimated risk of disease before testing.

For most tests, the null hypothesis is that there is no relationship between your variables of interest or that there is no difference among groups. For example, in a two-tailed t test, the null hypothesis is that the difference between two groups is zero.
