regression  logarithmic curve fit Message #1 Posted by pieropiero on 2 Oct 2003, 9:37 a.m.
From the HP67 standard pack I have converted into qbasic language the linear, power, and exponention formulas as mentioned in pages 0302 thru 0304. They work alright but I am unable to make use of the logarithmic regression
curve fit. This will not give the correct results.
I do not need the qbasic program lines but I would like to
get the correct logarithmic regression formula. Any help
will be welcomed.
I have some spare HP items, such as HP41 complete with card reader and printer. Anyone interested?
