probit_spline2: quadratic spline specification model with probit link

In PointFore: Interpretation of Point Forecasts as State-Dependent Quantiles and Expectiles

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

probit_spline2(stateVariable, theta, ...)

Arguments

stateVariable	state variable
theta	parameter
...	...

Value

numeric level

Other specification models: constant(), logistic_linear(), probit_break(), probit_linear(), probit_spline3()

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))
