TUTORIAL HYPOTHESIS TESTING IN STATA YouTube

The concept of R^2 is meaningless in logit regression and you should disregard the McFadden Pseudo R2 in the Stata output altogether. Lemeshow recommends 'to assess the significance of an independent variable we compare the value of D with and without the independent variable in the equation' with the Likelihood ratio test (G): G=D(Model

The Likelihood Ratio Test in High-Dimensional Logistic

The likelihood ratio test (LRT) compares the likelihoods of two models where parameter estimates are obtained in two parameter spaces, the space and the restricted subspace . In the GLIMMIX procedure, the full model defines and the test-specification in the COVTEST statement determines the …

Summary. You use the G–test of goodness-of-fit (also known as the likelihood ratio test, the log-likelihood ratio test, or the G 2 test) when you have one nominal variable, you want to see whether the number of observations in each category fits a theoretical expectation, and the sample size is large.

In the wound-healing assay solvent-treated SW620, LS174T, and SW480 cells were able to close the wound by day 4 after wound insertion . In contrast, in solvent-treated DLD-1 cells wound closure was not completed by day 4, which was consistent with their decreased migration and invasion rates. Following a single dose of 1 μM calcimycin, wound closure, as measurement for directed migration, …
