Announcing xldlas v0.30

=======================

I have recently placed version 0.30 of xldlas

in sunsite's incoming directory:

ftp://sunsite.unc.edu/pub/Linux/incoming/xldlas-0.30-srcbin.tgz

I expect it to be moved to:

ftp://sunsite.unc.edu/pub/Linux/apps/math/xldlas-0.30-srcbin.tgz

shortly.

What's New

==========

* One Way and Two Way Analysis of Variance (ANOVA).

Try it out under the Analysis menu. See help

Analysis --> ANOVA and the fourth tutorial.

(suggested by "Richard B. Kreckel"

* Scatter Plots.

Just double-click on a highlighted variable's name

in the Y-Variable browser (in the plotting window)

and set the line type to 0.

* Regression output now includes probability values.

The F-Test of the regression and the t-tests for

coefficient estimates are now included, so you

can see their significance without having to look

up any values in distribution tables.

* Changed object gravity in most windows so that resizing

works sensibly.

(thanks to "Richard B. Kreckel"

* Log and TeXLog now activated even if you don't hit

return in the file name requestor.

* Temporary files are much improved and are actually

removed when xldlas is finished with them.

(thanks to "Richard B. Kreckel"

* External declaration of **environ variable, which

is apparently useful for compiling under Solaris (and

should have been there for Linux in any case).

* Generate operations on (current) now work. That is

you can +,-.*,/ (current) and the data actually

changes.

What is it?

===========

It's for doing statistics.

Anybody Got Web Space?

======================

I'd really like to give xldlas a home page with information, screen

shots, links to xforms etc. I'm happy to write all the relevant html

documents, but my ISP has such a limited hit level that I just can't

afford to provide the web space myself. If you have zero cost (to

you) www space and would like to host the xldlas home page, then

Highlights

==========

* Based on the xforms library (ie. looks pretty slick)

* Point and click interface to statistical summaries, OLS

regression, plotting, correlation analysis, etc.

* Experimental curve fitting routine that uses genetic algorithms

with some nice visual feedback.

* Very handy automatic generating of .tex format log files,

including tables and plots.

* Online help

Where'd the Name come from

==========================

xldlas was inspired by a non-X statistics program called ldlas,

which stood for ldlas, damned lies, and statistics. So, I guess

xldlas stands for x ldlas, damned lies, and statisitics.

Feedback
