probit_spline2 function

quadratic spline specification model with probit link

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.

probit_spline2(stateVariable, theta, ...)

Arguments

• stateVariable: state variable
• theta: parameter
• ...: ...

Returns

numeric level

Examples

# plot example of quadratic spline specification model with state-dependent quantile/expectile level
plot(function(x) probit_spline2(x,theta=c(0,1,-1)), xlim=c(-2,2))
