How can I perform the likelihood ratio, Wald, and Lagrange multiplier (score) test in Stata?
摘要:http://www.ats.ucla.edu/stat/stata/faq/nested_tests.htmThe likelihood ratio (lr) test, Wald test, and Lagrange multiplier test (sometimes called a score test) are commonly used to evaluate the difference between nested models. One model is considered nested in another if the first model can be gener 阅读全文
