difference_test.pro

Name:　　difference_testPurpose: 平均値検定を行うプログラム。 χ二乗検定によって正規分布との適合を検定する。 どちらも正規分布に従う場合はWelch検定 どちらかが正規分布に従わない場合はマンホイットニー検定のみを用いる。Syntax: difference_test,x,y,result,sl=**Keywords: result:検定結果を'0'：ウェルチ検定使用-判定は異,'1'：ウェルチ検定使用-判定は同,'2'：マンホイットニー-異,'3'：マンホイットニー-同、で返す sl:有意水準。指定しない場合はsl=0.05で検定。 test_sel：行う検定を指定。'2'はマンホイットニー検定、'1'はウェルチ検定、'0'はχ二乗検定によって正規分布との適合を検定 2012/12/13 改変　by 濵口

mann_whitney_test.pro

NAME: Mann_Whitney_testPURPOSE: Test the difference for distributions between two data sets.
