Great post! I actually have a question about the model form of hazard analysis. I’ve been using the book “survival analysis using SAS”(very useful!) and it seems all the models in the book use a exponential form: h=exp(a+b*X1+c*X2), say h means hazard, and X1,X2 are the independent variables.

Jan 17, 2015 · In previous posts I’ve looked at R squared in linear regression, and argued that I think it is more appropriate to think of it is a measure of explained variation, rather than goodness of fit. Of course not all outcomes/dependent variables can be reasonably modelled using linear regression.

Bivariate associations between demographic characteristics and outcome variables appear in Table 1.Women, racial minorities, liberals, younger individuals, and those with at least one psychiatric diagnosis perceived themselves as more vulnerable to persistent negative emotional effects in the event of trauma than did men, Caucasians, conservatives, older participants, and those without a.

In R predict.lm computes predictions based on the results from linear regression and also offers to compute confidence intervals for these predictions. According to the manual, these intervals are.

Survival analysis is a branch of statistics for analyzing the expected duration of time until one or more events happen, such as death in biological organisms and failure in mechanical systems. This topic is called reliability theory or reliability analysis in engineering, duration analysis or duration modelling in economics, and event history analysis in sociology.
