3 1. Introduction FreeJSTAT is free statistical software for Windows. When it is installed, its source code is copied to the install folder by the name of sourcecode.zip. You can use it to develop your own software. However, I am not responsible for any damages your application may cause. Operating System FreeJSTAT runs on WindowsXP, WindowsVista, Windows 7, Windows 8, Windows 8.1, and Windows 10. It doesn t run on any other operating system. How to Use Before you start a statistical analysis, you have to set its data. There are eight types of data, which are Selected Column, Oneway Two Groups, Oneway Three Groups or More, Twoway Data, Selected Cells, Multiple Regression Data, Principal Component Analysis Data, and Discriminant Analysis Data. [Statistical Analyses for Selected Column] Summery Statistics Frequency Distribution Thompson s Rejection Test Smirnov-Grubbs Test Histogram [Statistical Analyses for Oneway Two Groups] F Test Paired t-test Unpaired t-test Wilcoxon Signed Rank Test Mann-Whitney U Test Regression Line Regression Curve Spearman s Rank Correlation Kendall s Rank Correlation Scatter Plot Line Plot (Oneway Two Groups) Line Plot (Oneway Two Related Groups) 3

5 Sample files copied to the install folder are as follows: ONEFAC.STJ: TWOFAC.STJ: SOUKAN.STJ: BUNKATU.STJ: ONEWAY.STJ: TWOWAY.STJ: JUUKAIKI.STJ: SHUSEI.STJ: HANBETU.STJ: LOGISTIC.STJ: Sample for Selected Column Sample for Oneway Two Groups Sample for Correlation Sample for Contingency Table Sample for Oneway Three Groups or More Sample for Twoway Data Sample for Multiple Regression Analysis Sample for Principal Component Analysis Sample for Discriminant Analysis Sample for Logistic Reression Analysis Their links are in FreeJSTAT menu bars. Notes -Data Sheet has only 100 columns. You cannot increase the number of columns. -You can input only numbers in cells except those in label column or in label row. -FreeJSTAT can read text files with less than 101 columns only when their seperaters are tab or comma. -There are some limitations to the number of data groups in some statistical analyses. -In nonparametric tests, the total number of data must be less than The change in the number of rows will be updated after you restart FreeJSTAT.
