Hi all,
I am having some trouble applying the ;export command, specifically the
resultant .csv file contains coefficients and standard errors etc. that are
(sometimes very) different to those presented in NLOGIT.
I am using the syntax below:
OPEN
;EXPORT="<filename>.csv"$
NLOGIT
;lhs=choice, cset,alti
;Choices=a,b,c,n
;tree=switch(a,b,c), noswitch(n)
;ivset:(noswitch)=[1.0]
;start=logit
;maxit=100
;export output
;Model:
etc $
In the exported file, the first attribute information appears to be
correct, however the second coefficient onwards exports incorrect
information. Example below (please excuse formatting, I am not a listserv
pro):
NLOGIT output:
--------+--------------------------------------------------------------------
| Standard Prob. 95%
Confidence
CHOICE| Coefficient Error z |z|>Z* Interval
--------+--------------------------------------------------------------------
|Attributes in the Utility Functions (beta)
Att1| -.01437 .24718 -.06 .9537 -.49884 .47011
Att2| .07179 .17488 .41 .6814 -.27097 .41455
Att3| .12039 .29830 .40 .6865 -.46427 .70505
Excel .csv output:
Variable Coeff. Std.Err. t-ratio P-value
Att1 -1.44E-02 0.247185 -5.81E-02 0.953656
Att2 -0.498839 0.470108 7.18E-02 0.17488
Att3 0.410522 0.681423 -0.270966 0.41455
Advice much appreciated.
Best wishes
Matt
