Inverse Linear Calibration Function

Description

inver.calib uses the inverse frequentist approach to estimate an unknown X given observed vector y0 and calculates confidence interval estimates.

Usage

1
inver.calib(x, y, alpha, y0)

Arguments

x

numerical vector of regressor measurments

y

numerical vector of observation measurements

alpha

the confidence interval to be calculated

y0

vector of observed calibration value
