This is a small application to calculate the slope, intercept, their
errors, and the correlation coefficient for a series of x,y data.
(i.e. y=mx+b). It should be of interest to any body wanting easily accessible linear correlations on experimental data.
This is a useful, small programme which could have been accomplished in excel, but I wanted to learn to programme the Macintosh.
Each cell is able to be typed into directly (Like 123, cricket graph, kaleidagraph, and unlike excel). Extra long numbers (up to 255 digits) are supported. Each cell can be moved to a more convenient place by option clicking on the extra long number (thanks MacTutor). Copying and Pasting from other graphing programmes is supported as well as Drag and Drop are supported (in a fashion).
This version will handle only 40 rows of xy data, but this can be increased to any value if you give let me know.
It is Freeware.
Source code is available for those who want to see how the File Manager, Sane, List Manager, etc. are used by a beginner!!
Please e-mail me if you want anything else added or something changed. It was designed for in-house (well, in department use) so isn't particularly polished and with luck should be pretty stable.
There may be some minor problems with NowMenus and auto-reopen of previous files. Just close and re-open and then recalculate. No worries!
Tested on a LCII (system 7.0.1) and IIci (7.1) without problems.

Please e-mail me if you even try this. I'd be interested to hear where it's arrived!!!
