From the HP-67 standard pack I have converted into qbasic language the linear, power, and exponention formulas as mentioned in pages 03-02 thru 03-04. 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 HP-41 complete with card reader and printer. Anyone interested?
