I made an initial attempt to implement a repeated measures anova. From that,
some questions arose about the reg_sweep function:
1. The comment says:
/*
LAST_COL is considered to be the final column in the augmented matrix,
that is, the column to the right of the '=' sign of the system.
*/
If I understand the theory correct, this should read "to the LEFT of the =
sign" ??
2. Results from my initial experiments suggest that:
a) In order to do a factorial anova, we would need to run reg_sweep N times
where
N is this number of factor variables.
b) We need to add another variable to reg_sweep to tell it which variable
we're currently
interested in.
3. reg_sweep can't be used to calculate the intercept.
Do we need to do some extra work on reg_sweep, or am I using it wrong?
