在matlab里面怎样做卡方检验

创建结构元素： >>clearclose all >>岩余晌键 SE = strel('rectangle',[40 30])%注意:结构元素必粗谨滚须具有适当的大小,既可以删电流线又可以删除矩形.

chi2gof

Chi-square goodness-of-fit test

Syntax

h = chi2gof(x)

[h,p] = chi2gof(...)

[h,p,stats] = chi2gof(...)

[...] = chi2gof(X,name1,val1,name2,val2,...)

vartest

Chi-square variance test

Syntax

H = vartest(X,V)

H = vartest(X,V,alpha)

H = vartest(X,V,alpha,tail)

[H,P] = vartest(...)

[H,P,CI] = vartest(...)

[H,P,CI,STATS] = vartest(...)

[...] = vartest(X,V,alpha,tail,dim)
