how to reset slogic.f file
Hi there:
recently i try to use LogicReg package for a tree model(logistics fit )
. i list my code and error below:
> dim(model.dat)
[1] 48000 745
> fit1 <- logreg(resp = model.dat[,745], bin=model.dat[, 9:700], type = 3,
select = 3, ntrees = c(1,2), nleaves=c(1,7), )
Insufficient declaration
LGCn1MAX in logreg() is 20000
LGCn1MAX should be at least 48000
Please fix and recompile....
i find the help file which said i need to reset them in *slogic.f* and
recompile if the parameters are not large enough. but i cann't find the
slogic.f .

How to get confidence interval and coefficient in Logic Regression
...(X,z,Y)
set.seed(12345)
Annealing <- logreg.anneal.control(start = 4, end = -4, iter = 1000, update
= 50)
logicfit <- logreg(resp=model.dat[,10],
bin=model.dat[,1:8],sep=model.dat[,9],
type = 3,
select = 2,
ntrees=2,
nleaves=3,
anneal.control=Annealing)
use names(logicfit) , i didn't see coef class. how to i get the
coefficient of the model , especially for the additive effect.
is there command i can calculate the sd so that i can have confidence
interval.
model.dat2<-model.dat
