NewStat4P  Curve fitting with linear, logarithmic, power and exponential equations  J E PattersonStat4P.15c  Curve fitting zipfile  DownloadStat4P.15c  Curve fitting with linear, logarithmic, power and exponential equations  Documentation This program provides linear, logarithmic, power and exponential regressions with a single entry of a data set. After r is displayed you can enter x' for an estimated y'. Repeat for more values of x. This applies for all regression models.
IntroductionThe first 5 programs below are bonded collections of smaller programs. Calling the appropriate label will run the desired program. Themes include Maths, Cycling and Physics. Use the references in the documentation to find the original programs or use this index to find some others. Collections can be created using a simple text editor by cutting and pasting smaller programs into one file. The line numbering will be fixed once the Simulator saves the composite file. Documentation can be created in a similar way, mostly by pasting lines beginning with #D: and adding new headings. The documentation includes a program listing.

StrayLightP  Stray light curve correction  J E PattersonStraylightP  Curve Fitting  DownloadStrayLightP  Stray light curve correction  Documentation Spectrophotometers have some stray light or detector dark current which causes the calibration to be non linear at high absorbances. This program corrects for the calibration curvature caused by the presence of stray light. CurveP  J E PattersonCurveP  Curve Fitting DownloadCurveP  Curve Fitting  Documentation The program fits data that may be linear at low x,y amplitudes but y falls off at higher x values. This is a common issue in many physical systems. x1, y1 should preferably be on the linear part of the curve. CurveP is not a regression. It assumes that the data is reasonably precise. Linear and power fit data sets also work well.
