-
- * linreg.c (pspp_linreg_with_cov): New function to estimate
- parameters directly from covariance matrix instead of using the
- entire data set.
-
- * linreg.c (rearrange_covariance_matrix): New function to ensure
- the columns of the covariance matrix correspond to the variables
- in the model.

-2008-07-24 John Darrington <john@darrington.wattle.id.au>
-

- with case ordering. This ensures that the casereader returned by
- sort_execute now has the same dimensions as the casereader passed
- in.
