NettetA multiple linear regression will have a t test, while a logistic regression will have a χ 2 test. This is used to determine the p value. p – this is used to determine which variables are significant. Typically, any variable that has a p value below .050 would be significant. In the table above, Variable 1 and Variable 2 are significant. Nettet12. mai 2024 · To do this, we simply split it in half so that an equal proportion of the area under the curve falls in each tail’s rejection region. For α = .05, this means 2.5% of the area is in each tail, which, based on the z-table, corresponds to critical values of z ∗ = ±1.96. This is shown in Figure 7.5. 2.
