Logistic

X Y Freq Category
Logistic , [, [ ] [,
Fits a logistic regression model to X and Y with frequency Freq. A
summary of results is stored in the stat.results variable. (See page
76.)
Output variable
stat.RegEqn
stat.a, stat.b, stat.c
stat.Resid
stat.XReg
stat.YReg
stat.FreqReg

LogisticD

X Y Iterations
LogisticD , [ , [
Calculates the logistic regression. A summary of results is stored in
the stat.results variable. (See page 76.)
All the arguments must have equal dimensions except for Include.
X represents xlist.
Y represents ylist.
Freq represents frequency.
Category represents category codes.
Include represents category include list.
Iterations specifies the maximum number of times a solution will be
attempted. If omitted, 64 is used. Typically, larger values result in
better accuracy but longer execution times, and vice versa.
