Hi, I'm new to the glm and logit world... and I'm reading some lecture
notes
and examples. I would like to try and generate the same result in R.. but I
don't seem to be able to find the proper way to specify the formula....
let's say i have
Desire Using Drugs Not Using Drugs
Yes 219 753
No 288 347
Desire is my explanatory and Drugs Using is my response...
How can I specify the null model? Namely
logit(pi) = n
where mle should give n to be logit((219+288)/(753+347))
Also, if I want a one factor model
logit(pi1) = n
logit(pi2) = n + alpha
where mle should give me n to be logit(219 / 972) and alpha be
logit(288/635) - logit(219/972)
Thanks!
