In using the likelihood ratio test for the hypothesis concerning the slope parameter in logistic regression model, we usually make use of the fact that the null distribution of the test statistic is approximately chi-square with one degree of freedom . The performance of the approximation for ...
To: statalist@hsphsun2.harvard.edu Subject: Re: st: conditional likelihood ratio test when the cluster option is used in ivreg (weak instrument). Professor Austin, Your advise helped me very much. I performed the AR test with the cluster option and obtained very good result. I only want ...
I'm confused about getting different results when trying to perform the likelihood ratio test (LRT) with R in different ways that are supposed to be equivalent. Below is the R code with some simulated data. I use GAM model with one predictor, whose significance I want to...

2015). Whenever the random component did not contribute to a better model using the likelihood ratio test, a more simplistic linear regression model was used. Whenever a model was significant using an ANOVA test, we computed a post hoc analysis using the lsmeans package (Lenth 2016). All ...

Using these results, we consider the problem of testing that one or several GARCH coefficients are equal to zero. The null distribution and the local asymptotic powers of the Wald, score and quasi-likelihood ratio tests are derived. The one-sided nature of the problem is exploited and ...
If it wasn’t a test in the first place, you will drastically reduce your chance of getting her. If one of her friends is flirting or hooking up with some guy, she may talk with them a bit to find out if he is a cool guy. Women use each other for screening men. (It’s why ...
When full models differed significantly from null models, likelihood ratio tests were conducted to obtain the p values for each test predictor via single-term deletion51. An α-level of 0.05 was adopted for all tests (but trends were considered when the α-level was between 0.05 and 0.10),...
