the chidist() function returns the probability value from the indicated chi square that a hypothesis is confirmed.
chidist () 返回来自假设确认的λ方指示的概率值 。

if the chi square value of the random sample is 13.27 and if the experiment has 5 degrees of freedom, then the hypothesis is assured with a probability of error of 2%.
抽樣的 chi 正方形數值總計為 13,27，而實驗的 degrees_freedom 為 5，因此誤差概率假設值確定在 2%。

chidist compares the chi square value to be given for a random sample that is calculated from the sum of (observed value-expected value)^2/ expected value for all values with the theoretical chi square distribution and determines from this the probability of error for the hypothesis to be tested.
chidist 比较随机样本的λ方值和λ方分布理论值， 从这个误差概率来决定假设检验的结果。 随机样本的λ方值是对于所有样本数值计算( 观察值 - 期望值) ^2/ 期望值， 然后求和得到的 。
