Dear All:

I face a difficulty with the command -fistat- (downloadable from SSC) after -ologit-.

Here is my command line:

ologit format size1 auditor_d standards_d for_list lev2 sales_int3

I get the follwing output:

Iteration 0:   log likelihood = -174.80658
Iteration 1:   log likelihood = -144.54522
Iteration 2:   log likelihood = -142.07299
Iteration 3:   log likelihood = -141.96804
Iteration 4:   log likelihood = -141.96723
Iteration 5:   log likelihood = -141.96723

Ordered logistic regression                       Number of obs   =        199
                                                  LR chi2(6)      =      65.68
                                                  Prob > chi2     =     0.0000
Log likelihood = -141.96723                       Pseudo R2       =     0.1879

When I type -fitstat-, I get the follwing error message:

fitstat

Measures of Fit for ologit of format

[_cut1] not found
r(111);

I must tell that I am very surprised because:

- fitstat works perfectly after -mlogit- (with the same dataset)
- fitstat used to work perfectly a few weeks ago with the same dataset after -ologit-, before I switched to Stata 9 (from Stata 8.2).

When I read the -fitstat- help file, it's still written that this command can be used after -ologit-.

Obviously, I miss something about -ologit- (or -fitstat-).

Best regards

Hervé Stolowy
