The coefficients on the level x terms are the long-run effects. This
helper extracts them and stores them in the fit's lr_coef and
lr_vcov fields so that downstream S3 methods can print a long-run
block.
.csdl_postprocess(fit, lr_names)Augmented fit object.
A dcce_fit object.
Character vector of x level names whose coefficients are the long-run effects.
