請問一下應怎麼判斷所求的B~χ2(df=1)的假設是拒絕還是保留? 是不是在 excel 輸入 CHIDIST function: =chidist(B,1) <--這就是p_value 再判斷此值是不是大於0.05 若大於0.05 則保留 Ho的假設 變異數同質?? 因為看到下面的文字不太懂它的意思的 麻煩幫我看一下 謝謝 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惡之故有道者不處君子居則貴左用兵則貴右兵者不祥之器非君子 之器不得已而用之恬淡為上勝而不美而美之者是樂殺人夫樂殺人者則不可得志於天下 矣吉事尚左凶事尚右偏將軍居左上將軍居右言以喪禮處之殺人之眾以哀悲泣之戰勝以 喪禮處之道常無名樸雖小天下莫能臣侯王若能守之萬物將自賓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將知止知止218-169-41-138.dynamic.hinet.net海
