[Limdep Nlogit List] estimate the elasticity

[邱順波]

Dear all:
        I estimated the elasticity, using "effects:INTU(*)" in limdep.
The set of results as shown in the following:

choice=s1.......3.350 3.350
*choice=s2.......-7.177 -7.177
choice=s3.......3.350 3.350

* indicates direct Elasticity effect of the attribute.

so, I can explain the direct elasticity effect --the effect of a change in
INTU in choice s2 one the probability that individual would choose
alternative s2 is -7.177. Right?
now, I have one question about ...why the effects on probabilities
of  choice s1 & s3 both are 3.35.
Is it right? how to explain it?

Please help me, thanks.
