commit ef40d0ff4989b13360acb0504ac5a8fbeff31c16
Author: John Darrington <address@hidden>
Date: Sat Oct 31 09:02:32 2009 +0100
Wrap operations which index into reverse_variable_map
New private function reverse_variable_lookup. This
function wraps operations which index into the array,
and includes checks to prevent indexing outside the
bounds of the array.
commit a741cf4e8348e478ec5e8658cebeb80dc0376b1a
Author: John Darrington <address@hidden>
Date: Sat Oct 31 08:42:25 2009 +0100
Drop first category of each variable from covariance matrix.
Apparently it's not appropriate for the covariance matrix to
have a row/column for every categorical value. One value per
categorical variable should be excluded. This change drops
the first category encountered.
commit 5055ec22100c84153e76662bae23063408a6a935

Remove unused function categoricals_index

Author: John Darrington <address@hidden>

Populate the moment matrices with the categorical entries
commit 46fdaed173d06e42dac6712e142bc9f7898075d7
Author: John Darrington <address@hidden>
Date: Sat Oct 31 08:04:32 2009 +0100
Keep track of the number of variables involved in the categoricals.
Added a counter for the number of variables which actually contribute
to categories. Due to the possibility of missing values, this may
not be equal to the number of variables passed to the contructor.
commit 11b8d81d6f403209b15bdf5a58ed2b98cd4ee3bb
Author: John Darrington <address@hidden>
Date: Sat Oct 31 07:04:25 2009 +0100
Don't crash if all categorical variables are empty
