An object produced by lm fitting. |
Columns containing different elements of a singular vector are labelled either as (Intercept) or by the variable name.
Returns the table of condition indices and model matrix right singular vectors for the chosen model, with singular vectors appearing as rows next to the corresponding condition index.
