probit_spline2 {PointFore}

quadratic spline specification model with probit link

Description

All specification models can be used as parameter in estimate.functional. Specification models are used to denote the quantile or expectile level (depending on the identifciation function). This specification model depends through a quadratic spline on the state variable and applies a probit link function.

Usage
