I am using some logistic regression testing and I have received this message.
Not quite sure what this means...
My coefficients are pleasingly significant. I performed an AUTO CORR command to see whether autocorrelation could corrupt my results however the results are good. So is this message "Convergence criterion (GCONV=1E-8) satisfied" normal?
The screen image is very fuzzy, I can't read everything. The error says that among the observations where all variables are not missing (only those are considered) the dependent variable always has the same value. This could be caused by all the logs involved, if missing values were generated when calculating them, in a previous step.
I have received a warning message saying "ridging has failed to improve the log likelihood" and the validity of the fit is questionable.
I have four different dummy variables in this regression, the dependent, and three control independents. Do you think this could cause the error?
I have checked for duplicates, blanks in the dummies, and auto correlation, all seem to be OK
This note means that the relative gradient (max of the first derivatives wrt to the fixed effect parameters)/ absolute value of the objective function has reached a near zero value (0.00000001), thus you are at a maximum/minimum/saddle point of the objective function. Changing parameter values won't improve the fit to the data.
