Surf ver 3.1, by Scott Guth
Surf is a fast SysRPL 3D surface plotter for the HP48 with hidden line removal. Surf is the fastest program of its type for the HP48 (in my never-to-be-humble opinion). Surf allows you to view your surface from any angle. Version 3.1 includes a trace mode as demonstrated below. The surface images and animations on this page were all generated by Surf.
Above is an example of Surf's new TRACE mode. Note the behavior at the point of discontinuity.
Stat48, Stat48L and Stat49 ver. 2.1, by Scott Guth
Stat48/49 is a utility for performing hypothesis tests and confidence intervals. Included are hypothesis tests and confidence intervals for single population mean, single population proportion, single population standard deviation, two population means (dependent or independent), two population variances, two population proportions, analysis of variance (one or two factor), contingency tables, goodness of fit, and the linear correlation test. P values are computed for each test, along with test statistics and critical values. Also included are critical values for the normal, t, F and Chi-square distributions. Notation is standardized since version 1.3. Version 2.0 includes confidence intervals for two independent sample means, and gives the user more control over how tests are performed (especially with regard to pooling of variances, whether variances are known on means tests with small sample sizes, along with ability to define how large is a "large" sample size, and to define the round-off amount). Version 2.1 includes minor source-code modifications for HP49 compatibility. Stat48 Light (Stat48L) is smaller for running on the HP48G calculator. Stat49 runs on the HP49G calculator.
