Let m be the number of independent variables,
ivs.' This function returns<br> a vector of length m which are the coefficients of a linear equation that best<br> predicts the dependent variable, dv,' in the least squares sense.
This function returns the minimal information for a least squares regression
model, namely a list of the coefficients of the ivs, with the constant term
first. Consider using the sibling functions -brief and -verbose if you want
