Estimating the calibration equation “y=a+b*x” with error-in observations assuming that the coefficients of the variation of the measurements are constants.
1 | calfun(x, y, CVx, CVy, lambda0)
|
x |
The observed $x$ values |
y |
The observed $y$ values |
CVx |
The underlying coefficient of variation of measurement $x$ |
CVy |
The underlying coefficient of variation of measurement $y$ |
lambda0 |
The ratio, $CV_y^2/CV_x^2$ |
result |
The estimated regression coefficients, standard error and confidence intervals based on (1) CVx only; (2) CVy only; (3) both CVx and CVy; and (4) the ratio of CVy^2/CVx^2. |
