Automatic Developing Chamber for TLC

Statistical Software SigmaStat is a statistical software package that performs such computations as t tests, analyses of variance, correlations, rates and proportions, nonparametric methods, linear and nonlinear regressions, and power and sample size analyses. SigmaStat's procedures are automated and require little statistical knowledge from the user. An "Advise" command helps the user select the most appropriate statistical procedure for the data and then automatically performs the test. The program also checks that the user's data fit the assumptions underlying the selected statistical methods, warns the user if they are violated, and automatically suggests and computes more appropriate alternative tests. Data import options include text, spreadsheet, database, and SigmaPlot files. The program requires an IBM-compatible computer, DOS 3.0 or higher, a hard disk with 3 megabytes free, and 535K conventional memory or 510K with extended memory. Jandel Scientific. Circle 89.
