|Statistical analysis galore|

Ok, the roll never stopped. I finally caught up with my HP-41 back-log.
A few months ago I posted a rather mammoth STAT-program. It is mainly the excellent program from William Kolb, but with added basic statistics, momentums, kurtosis and skewness of data and with a proper user interface via menus.
Some, very understandably, asked for documentation of the STAT program (reading through the 1122 program steps to figure it out was hard enough for me tonight). I finally got around to documenting it just now.
The brother of the STAT program is a program called DATA. It simplifies working with data sets on the 41. With DATA you can create single (one value) data sets or double (X and Y) data sets, save it to XM, retrieve it from XM, add more data points, save it back to XM, work with fixed size data sets (e.g. or 12-months rolling data sets), remove data points, print the data sets as a graph on a printer and more.
Along with the file management system posted earlier, you will have the mother of all data set and analysis programs on you HP-41.
Here is the STAT and DATA programs .
Testing for bugs and enhancements are very welcome.
