[Limdep Nlogit List] Clarification

[Anushiya Thanapalan]

Hello,
 I'm using NLOGIT to run a multinomial logit model. The output did not provide the pseudo R squared value. Rather, it gave the following: R-sqrd = 1 - logL/Logl (constants). What does it all mean? Does this imply that I must perform a manual calculation to determine pseudo R squared? I looked through the documentation but couldn't find a suitable answer.
Regards,
Anushiya
