I am fitting PO models to ordinal categorical data, and wish to apply fractional polynomials to the continuous covariates.  However, fracpoly does not allow ologit as the regression command.

Is there a work-around? Or some other way of achieving my aim?

Many thanks in advance for any assistance with this.
