Greetings all,

I am using meqrlogit to predict binary outcome (use of potentially harmful medication class in older adults) using ten binary individual level predictors and time (24 quarters), clustered within state.

code takes form: meqrlogit y x1 x2 x3 x4 x5 ..., noconstant || state:

For the first 155 iterations the log likelihood value changed with each iteration, however the last 14 iterations have produced identical log likelihood values.

This is a large dataset (25 million observations) and the model has been running for 14 days. There has been no change in the log likelihood value for more than 24 hours.

Has anyone experienced similar issue? Is there a way to salvage starting values if I break/stop the model?

Analysis is run in high security environment without internet access, please forgive inability to copy text/data/output.

Many thanks in advance for advice and insight.

Respectfully,

Olga
