[rkward-devel] Second call for testing: RKWard 0.5.3-pre2

[mat]

On virtualized ubuntu 9.10, 32 bits, R 2.11, eRm 0.12

Avis dans Waldtest.Rm(rsm.res) :
 
The following items were excluded due to inappropriate response patterns 
within subgroups:
I2 I3 I4 I5
Subgroup models are estimated without these items!

Wald test on item level (z-values):

           z-statistic p-value
beta I1.c1       0.388   0.698
beta I1.c2       0.048   0.962
beta I1.c3       0.049   0.961
beta I6.c1      -0.388   0.698
beta I6.c2       0.045   0.964
beta I6.c3       0.047   0.962

But I don't have warnings as German has
