fastbw question
...Design library fitting function; yet when I
go to the help for fastbw (and also look in Frank's book Regression
Modeling Strategies) it appears that fastbw should work with a model
created with lm.....
Relevant code
<<<<<
model.borrow.logols<- lm(logborrow~age + sex + racgp + yrseduc +
needlchg + gallery + totni + inject + poly(year.of.int,3) + druginj
+ inj.years + HTLV3)
fastbw(model.borrow.logols)
>>>>
Thanks in advance

polr and optim question
Hello again
I am trying to fit an ordinal logistic model using the polr function
from MASS. When I run
model.loan.ordinal <- polr(loancat~age + sex + racgp + yrseduc +
needlchg + gallery + sniffball + smokeball + sniffher +
smokeher + nicocaine + inject + poly(year.of.int,3) + druginj +
inj.years)
I get an error
Error in optim(start, fmin, gmin, method = "BFGS", hessian = Hess, ...)
:
non-finite value supplied by optim
I checked in...
