在没有明确地指明备择假设时,我们通常都认为备择假设时双边的,同时,Stata 回归中报告的p 值(第4节内容)都是检验参数为 0 的双边备择假设。 双边备择假设也很好理解,在 3.1 节的单边备择假设检验中,我们只关心系数是否”极左“”极右“。如果原假设是参数等于 0 ,备择假设是参数大于零,那么只有在 t 值比较...
Note that when there are only two groups for the one-way ANOVA F-test, F=t2 where t is the Student's t statistic. Software implementations Many spreadsheet programs and statistics packages, such as QtiPlot, LibreOffice Calc, Microsoft Excel, SAS, SPSS, Stata, DAP, gretl, R, Python, PSPP...
