Obviously, group 4 has higher values than any other group but only the difference with group 3 reaches statistical significance.Ī few other post-hoc tests are available, such as the Bonferroni multiple-comparison test (option b). In STATA one can just run logit and logistic and get odds ratios and confidence.

0528 lower than the value of group 2, but this difference is not statistically significant. This tutorial explains how to execute a Breusch-Pagan Test in R. 0673 lower than the value in group 1 this difference is statistically significant at the 5 per cent level. 0145 lower in group 2 than in group 1, but the difference is not statististically significant.

F-tests can compare the fits of different models, test the overall significance in regression models, test specific terms in linear models, and determine whether a set of means are all equal. The results for the Scheffé test may look like this: The procedure is to first store a number of models and then apply esttab to these stored.
first is an F-test based on the idea that if a bin width is too wide, using narrower bins would. esttab namelist using filename, options estoutoptions. It can be obtained using the -lowess- command in STATA. Option sch or scheffe computes the Scheffé test for post-hoc differences between groups. esttab is a wrapper for estout.Its syntax is much simpler than that of estout and, by default, it produces publication-style tables that display nicely in Statas results window. and n of cases for each group and the total sample. Option t or tabulate yields a summary table with mean, s.d.
