Clarification regarding workInLogs

Hi forum admins,

Apollo manual suggests setting workInLogs to TRUE for complex models (like Hybrid Choice). The way I read it that should work for data without the panel structure too. However, when I set it up, I get the message "Working in logs is only applicable with panel data; workInLogs set to FALSE in apollo_control."

Can you please clarify the use of workInLogs in apollo 0.2.6? Thanks!

Hi

workInLogs is a setting that can avoid numerical issues in cases where there are many observations for the same individual leading to very small values in the product across observations. This feature is only implemented for cases where there are multiple observations per individual. Are you running into numerical issues with your cross-sectional model?
