A univariate model object of class lm or - rlm +

A univariate model object of class lm or + rlm with model formula y ~ x or y ~ x - 1.

Value

A plot of the calibration data, of your fitted model as well as lines showing the confidence limits. Prediction limits are only shown for models from unweighted regression.

Note

Prediction bands for models from weighted linear regression require weights for the data, for which responses should be predicted. Prediction intervals using weights e.g. from a variance function are currently not supported by - the internally used function predict.lm, therefore, + the internally used function predict.lm, therefore, calplot does not draw prediction bands for such models.

It is possible to compare the calplot prediction bands with the lod values if the lod() alpha and beta parameters are half the value of the calplot() alpha parameter.
