Description

Plot prediction intervals for simple linear regression

Usage

pred_interval_reg(
  lmobject,
  conf_int_line = T,
  pred_interval = T,
  level = 0.95,
  ngrid = 100
)

Arguments

lmobject	a fitted regression model from lm.
conf_int_line	if TRUE, then conf intervals for regression line are plotted.
pred_interval	if TRUE, then prediction intervals are plotted.
level	confidence level, default is level = 0.95
ngrid	number of grid points over which the intervals are computed

Value

data frame with confidence and prediction intervals over xGrid

Examples

library(regkurs)
lmfit = lm(mpg ~ hp, data = mtcars)
res = pred_interval_reg(lmfit)
