intervals: GAM confidence and prediction intervals

In pedersen-fisheries-lab/spaspm: Spatial Surplus Production Model Framework for Northern Shrimp Populations

GAM confidence and prediction intervals

Description

Computes CI from posterior, and PI for Tweedie and scat gams.

Usage

predict_intervals(object_fit, new_data, n = 1000, CI = TRUE, PI = TRUE, ...)

Arguments

object_fit	[gam OR bam] The fit to use for predictions.
new_data	[data.frame] The data to predict onto.
n	[numeric] The number of simulations to run for parameters.
CI	[logical] Whether to compute the CI.
PI	[logical] Whether to compute the PI.
...	further arguments passed to the quantile function.

Value

A data.frame with intervals.

Examples

gam1 <- gam(cyl ~ mpg, data=mtcars, family = tw)
predict_intervals(gam1)
