commit 4443108e98b43b196f3f07217c6ec8bd96581367
Author: John Darrington <address@hidden>
Date:   Tue Jul 2 19:41:16 2013 +0200

    Fixed incorrect behaviour of REGRESSION when multiple dependent variables 
are entered
    The REGRESSION command behaved badly when more than one dependent variable 
was entered.
    The cause was that the unnormalised covariance matrix returned from the 
    module was mutated for each variable.  Consequently, each variable after 
the first
    was wrong.  This change fixes that by changing the ownership semantics of 
the returned
    matrix (and thereby its constness).
    This change also adds some comments, attends to constness and fixes the 
    memory leaks associated with regression.

    Fix problems associated with LINEAR REGRESSION and splits

Author: John Darrington <address@hidden>

    Added test to check that REGRESSION works with multiple dependent variables

commit 7e413bbdf7b01f2ff0153c8cbf79c2e4fa71f4d5
Author: John Darrington <address@hidden>

    Added a test to ensure that SPLITS vs REGRESSION/SAVE works ok

    This way I can run just the linear regression tests without the
    logistic regression tests.
