Subject: [Limdep Nlogit List] Line search does not improve the function.
Message-ID: <E15864DD6A3923429EB835F66A61E923021BD087E8@MBOXDAG04.xjtlu.edu.cn>

Dear professors,

I am running a Nested Logit Model in NLogit v5.0.

I find the location of alternative specific constants (ASCs) in the utility function can impact the model convergence.

When I specify the utility function with 3 alternatives as:
U(A) = a1*X1 + a2*X2  /
U(B) = a1*X1 + a2*X2 + asc_b + age_b*Age + sex_b *Gender /
U(C) = a1*X1 + a2*X2 + asc_c + age_c*Age + sex_c *Gender
The model estimation shows that  Line search at iteration   61 does not improve fn. Exiting optimization.

However, when I make a minor change on the utility functions to
U(A) = a1*X1 + a2*X2  /
U(B) = asc_b+ a1*X1 + a2*X2 + age_b*Age + sex_b *Gender /
U(C) = asc_c + a1*X1 + a2*X2 + age_c*Age + sex_c *Gender
The model can successfully converge, with the exact same LL function, all estimated coefficients as well as standard errors as in the previous case (though not converged as mentioned in output).

I don't know what is wrong with the first case.

Thank you and appreciate your advices.


Best,
Lixian

Lixian. There is nothing wrong with either estimation.  The difference is
small
rounding error.  The message indicates that the log likelihood is
relatively flat
near the maximizer.  The two specifications are logically equivalent, but in
computing the logL, very small rounding error depends on the actual order
in
which the computations are done.

Charles.  The matrix for WTP is created before the program has detected
what type
of model will be computed.  The latent class logit model is a MNL model in
each
class.  Therefore, the WTP in each class is the same for every individual -
it is just the
same ratio of parameters for everyone.  Since it is not known which class
any individual
is in, it is not possible to discern which of those (two in your case)
ratio applies to a
given person.  For that reason, the matrix wtp_i is not filled.  It would
just be the same
value for each individual.

Bill Greene

Thank you very much for your reply. I have tried the "; ALL $" option at the end of the command, but the output did not change for the version I got without the "; ALL $" option.

To be more precise, this is (a part of) the matrix of elasticities that I get from the command shown earlier (augmented by the "; ALL $" option).



Any other way of getting the Standard Errors of these elasticities?

Many thanks
Federica

Dear Bill, 

to check whether the issue was the syntax used for my estimation command, I also estimated a simpler model specification, using this alternative syntax:

nlogit; lhs=choice,nij,altcode
      ; choices=AT,BE,BR,CA,CH,DE,DK,DOM,ES,FI,FR,GB,IE,IT,NL,NO,RU,SE,US 
      ;rhs=one,altstr 
      ;rh2=parstr 
      ;fcn=altstr(n)
      ;checkdata
      ;pds=3
      ;maxit=400
      ;alg=bfgs
      ;pts=100; halton
      ;effects:altstr(*)
      ; ALL $

Once again, the elasticities are only displayed in the format of a matrix, with no reported SE (see a partial pasted result below). Could the matter be the version of my software (NLOGIT5)?

Many thanks, 
Federica

Subject: Re: [Limdep Nlogit List] Standard Errors for Elasticities of Random Parameter Conditional Logit

Thank you very much for your reply. I have tried the "; ALL $" option at the end of the command, but the output did not change for the version I got without the "; ALL $" option.

To be more precise, this is (a part of) the matrix of elasticities that I get from the command shown earlier (augmented by the "; ALL $" option).



Any other way of getting the Standard Errors of these elasticities?

Many thanks
Federica

Federica.  Try adding ;ALL to the command, to request the full set of statistics for the elasticity.

Federica.  Try ;FULL.  I think that will generate output tables for the
elasticities.
