[Limdep Nlogit List] Latent class model

[中国海洋大学刘威]

Dear all
     Here is the code of the shallow category model, I have a few questions to ask you: 
     first of all, I return to the 2-6 shallow categories through the code, got specific indicators, different AIC and BIC results are as follows, there are five categories in AIC and McFadden Pseudo R-squared, but the coefficients in one of the five categories are not significant. There are four categories in BIC, and the coefficients in all four categories are good? 
| 　 | Class-2 | Class-3 | Class-4 | Class-5 | Class-6 |
| Log likelihood function | -2087.9153 | -2005.4998 | -1941.099 | -1908.51491 | -1909.18263 |
| McFadden Pseudo R-squared | 0.330809 | 0.3572237 | 0.3778646 | 0.388308 | 0.388094 |
| BIC | 4358.7 | 4321.1 | 4319.5 | 4381.6 | 4510.2 |
| AIC | 4221.8 | 4089 | 3992.2 | 3959 | 3992.4 |


     Second, I first broke it down into four categories, and then I calculated the WTP values and confidence intervals for the scenario attributes of each category through the following code, but it always says "Wrong number of start value -- need one for each Labal", and if my code is wrong, then how do I compute the WTP for each shallow category schema attribute?

   Thank you very much, hope to get your help!
