47 bytes of string variables into the output cells, seeing as we only
49 (dump_condensed) Ditto.
51 Mon Jun 19 21:52:05 2006 Ben Pfaff <blp@gnu.org>
53 Fixes a bug reported by Greg Hunt <greg@firmansyah.com>.
55 * frequencies.q: (hsh_hash_bytes) We only copy the first

101 Continue reforming procedure execution. In this phase, get rid of
102 the output code for SPLIT FILE groups in procedure.c, which really
103 shouldn't be doing any output. Move it into the individual
104 procedures instead. This also adds some flexibility.

122 Continue reforming procedure execution. In this phase, get rid of
123 many global variables, consolidating procedure execution in
124 procedure.c. Encapsulate transformations in new "struct
125 trns_chain". Also, change implementation of N OF CASES, FILTER,
126 and PROCESS IF from special cases to transformations.
128 * aggregate.c (cmd_aggregate) Use discard_variables().
130 2006-04-28 Jason Stover <jhs@math.gcsu.edu>
132 * regression.q (regression_trns_resid_proc): Pass only the
133 variables used in the model to (*model->residual)().
135 * regression.q (regression_trns_pred_proc): Pass only the
136 variables used in the model to (*model->pred)().

173 2006-04-20 Jason Stover <jhs@math.gcsu.edu>
175 * regression.q (cmd_regression): Moved call to subcommand_save()
176 outside multipass_procedure_with_splits().
178 * regression.q (regression_trns_proc): Fixed value counter n_vals
179 before calling *model->residual().

201 * regression.q (regression_trns_proc): New function.
203 * regression.q (subcommand_save): Create variable residuals and
204 add a transformation to assign values to them. Also free the

207 regression_trns_proc.
209 * regression.q (run_regression): Moved call to free
