Hi, R users,
I am using nlm function to get the MLE of parameter alpha and lambda from a
parametric survival model (Weibull distribution). However, this message

Hi, guys,
I am a new user for package R2winbugs. When I run the code a=bugs(...), an

Hi,
I am in trouble on doing poisson regression for a complex sample design

Hi,
I want to do logistic regression based on a complex sample design. I used
package survey, but when I ran svyglm, an error message came out:
