HP67: Gary Tenzer's Curve Fit / Best Function program
Based on this thread: http://www.hpmuseum.org/cgisys/cgiwrap/...ead=141284, I found the code for the HP67 version of Gary Tenzers curve fit / best function program here: http://hhuc.us/2013/files/Speakers/07%20..._Rev_C.pdf
Could someone who has the information please send me the usage instructions. Its not working for me and I am not sure whether I entered it wrong, or whether I am misunderstanding how it should be used. Thanks in advance.

Click on these thumbnails for the fullsize original pages from the PPC Journal. The corrections handwritten here were specified in a subsequent issue. I'll bet that's what was causing your troubles.

It turns out that I had entered the program wrong. I had misinterpreted the ISZI instruction. I only have an HP67 and the listing has the HP97 keycodes. It was only when I looked at a picture of the 97 that I understood my error. The link referenced in my original post does have all the handwritten changes incorporated. Program works like a charm.

Marcel,
I wrote a series of "best regression models" for the HP 39gII for HP Solve. These programs also work for the HP Prime. They perform best models selection among hundreds and thousands of models. I encourage you to search the HP Solve issues (look in late 2011 or early 2012 issues). YOU WILL NOT BE DISAPPOINTED! Namir

Namir, Thanks for the reference. I took a quick look and was not disappointed! I really like the approach. Did you ever adapt any of those routines to other calculators besides the 39gII? Marcel

Marcel,
Those are the ones! I am embarrassed to say that forgot about the copies of these articles being posted in my own web site! Namir
