Help on predict.lm
Hello,
I'm new here, but will try to be as specific and complete as possible. I'm
trying to use “lm“ to first estimate parameter values from a set of
calibration measurements, and then later to use those estimates to calculate
another set of values with “predict.lm”.
First I have a calibration dataset of absorbance values measured from
standard solutions with known concentration of

Regression query
Hi
I have a set of data with both quantitative and categorical predictors.
After scaling of response variable, i looked for multicollinearity (VIF
values)
among the predictors and removed the predictors who were hinding some of the

predictors. I'm curious to know whether the predictors (who are not
significant)
while doing simple 'lm' will be involved in
