Based on the provided code snippet, the issue seems to be related to the way you’re handling the adSingle parameter in your SQL query. When using an adSingle parameter with a value of type CSng, it’s likely that the parameter is being set to a string instead of a single-precision floating-point number. This can cause issues when trying to execute the query, as the parameter may not be treated as expected by the database engine.

Introduction to Mixed Logit Models and the mlogit Package in R As a statistical analysis tool, mixed logit models are increasingly used to estimate complex relationships between categorical variables.
