An xp_xtras example of the proportional odds categorical vismodegib model

The referenced work presents two alternative modeling approaches for muscle spasm response to vismodegib. This is a fit of the provided proportional odds model to the 50 participant mock data.

Usage

vismo_pomod

Format

xp_xtras

An xp_xtras object.

Examples

# To establish as a complete categorical DV example:
vismo_pomod <- vismo_pomod  %>%
  set_var_types(.problem=1, catdv=DV, dvprobs=matches("^P\\d+$")) %>%
  set_dv_probs(.problem=1, 0~P0,1~P1,ge(2)~P23)
