请问一下应怎麽判断所求的B~χ2(df=1)的假设是拒绝还是保留? 是不是在 excel 输入 CHIDIST function: =chidist(B,1) <--这就是p_value 再判断此值是不是大於0.05 若大於0.05 则保留 Ho的假设 变异数同质?? 因为看到下面的文字不太懂它的意思的 麻烦帮我看一下 谢谢 Calculate the Breusch-Pagan test score, B ~ χ2(1) . In this case, B = 0.4403. Get the p-value associated to the χ2 you just computed (with one degree of freedom). In Excel, you can use the CHIDIST function: =chidist(0.4403,1)=0.5070 You will obtain a p-value of 0.5070, so we cannot reject the null hypothesis. In the Breusch-Pagan test the null is homoskedasticity. -- 夫兵者不祥之器物或恶之故有道者不处君子居则贵左用兵则贵右兵者不祥之器非君子 之器不得已而用之恬淡为上胜而不美而美之者是乐杀人夫乐杀人者则不可得志於天下 矣吉事尚左凶事尚右偏将军居左上将军居右言以丧礼处之杀人之众以哀悲泣之战胜以 丧礼处之道常无名朴虽小天下莫能臣侯王若能守之万物将自宾天地相合以降甘露民莫 之令而自均始制有名名亦既有夫亦将知止知止218-169-41-138.dynamic.hinet.net海
