by 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.
