I was trying to fit spline into a multivariable logistic mixed model using the effect statement. However, there awas a warning in the log indicated "the 'Odds Ratio Estimates' table and odds ratio plots are not produced for models with constructed fixed effects." Does anyone know how to calculate the OR and output the OR?
Also, I would like to generate a plot as OR vs the variable used for spline while setting the other variables as constant. Does anyone know how to generate the plot?
Thank you very much!
