ARCUS-Pro REVISION 1.30
~~~~~~~~~~~~~~~~~~~~~~~
since 1.21...
ADDITIONS
~~~~~~~~~
1) Friedman Nonparametric Two Way Analysis of Variance with multiple
contrasts. The T2 statistic was defined by Inman & Davenport in
1980 and this is tested against the F distribution unlike previous
versions of the Friedman test statistic which were tested against
the chi-square distribution. Conover recommends T2 (ref 2).
2) Logit, Probit, Angular and Cumulative transformations have been added
to the `Arithmetical Manipulation Menu'.
ALTERATIONS
~~~~~~~~~~~
1) Many of the algorithms have been rewritten to improve speed and data
storage. You will find the ranking tests about 250% faster.
2) Arithmetical manipulations have been upgraded.
3) Pictorial statistics have been upgraded by removal of the scientific
format for axis labelling.
4) Correction of small error in upper confidence limit in Wilcoxon signed
ranks test.
ARCUS-Pro REVISION 1.41
~~~~~~~~~~~~~~~~~~~~~~~
A new module, ARC6.EXE, has been added. This introduces generalized linear
modelling into Arcus for the first time. Probit analysis is provided and
the normal sigmoid is fitted by maximum likelihood. This is intended for
use with quantal response data, such as dose-response curves. Relative
potency calculations are also provided.
This new module is now being developed further to allow other models to be
fitted by maximum likelihood optimisation.

All modules have been revised with respect to the efficiency of the programs
once again. This revision further improves storage space and speed of program
execution.
The formats of the instant functions have also been revised. Fisher's exact
test is now executed in double precision and larger tables are permissable in
the expanded test.
ARCUS-Pro REVISION 1.42
~~~~~~~~~~~~~~~~~~~~~~~
Variable selection method improved.
Better handling of data files with large numbers of variables.
Problem with MCGA monochrome monitors solved.
Handling of missing data in 2 way multiple measures ANOVA now included.
Ref: Armitage & Berry 1987
ARCUS-Pro REVISION 1.43
~~~~~~~~~~~~~~~~~~~~~~~
Problem handling missing data values in parametric tests fixed.
Exact alternative to McNemar's test now gives two tailed probabilities
which are more approprite than the one tailed given previously.
Final message in Shapiro-Wilk test has been corrected.
Menu system has been further improved.
