ci: Confidence Interval for the Changepoint

In blmr: Broken Line Model Regression

Description

Confidence interval for theta, the changepoint's x-coordinate.

Usage

## S4 method for signature 'Cblmr'
ci(  CL =0.95, method ="clr" )

Arguments

CL	confidence level, between 0 and 1
method	"clr" or "af" which stand for conditional likelihood-ratio, which is exact, or approximate-F

Details

This subroutine scans to determine the postulate values of theta that have significance levels greater than 1-CL.

Examples

##  Data for Patient B from Smith and Cook (1980):
y = c(37.3, 47.1, 51.5, 67.6, 75.9, 73.3, 69.4, 61.5, 31.8, 19.4)
x = 1:10
sc <- blmr(y,x)
sc$ci()
sc$ci(0.90)
sc$ci(.99,"af")
