在卡方检验中,最常用的就是Pearson卡方检验(Pearson's chi-squared test),它是一种非参数检验,适用于定类变量之间的关联性分析,可以用于衡量观察值与期望值之间偏离程度的统计检验方法。通过统计样本的实际观测值与理论推断值之间的偏离程度,实际观测值与理论推断值之间的偏离程度就决定卡方值的大小,如果卡方值越大...
测量两个连续变量之间的线性关系。 卡方检验 (Chi-Squared Test) 📈 用于比较观察频数和期望频数,常用于列联表。 线性回归 (Linear Regression) 📈 用于评估一个或多个预测变量与因变量之间的关系。 Logistic回归 (Logistic Regression) 📈 用于预测分类变量的结果,例如二分类问题。 多重回归 (Multiple Regressi...

> prop.test ( effect , total ) #x-squared=10.703,p-value=0.001 同理, prop.test ( effect , total ,correct = F) #不较正,11.713,0.000 所以在这里的话,我个人是觉得prop.test比chisq.test好用的,原因是:第一它显示的细节比chisq更多,比如它会显示比例之差的95%的置信区间;第二它的构造很方便,...

在SPSS中,可以通过查看Omnibus Tests的Chi-square值和相应的p值来实现。如果p值小于0.05,那么模型是显著的。📈 模型拟合的好坏: 模型的拟合度可以通过Hosmer and Lemeshow Test来评估,如果p值大于0.05,那么模型的拟合是良好的。此外,R-squared (Nagelkerke R Square)描述了模型解释的因变量变异的百分比,值越接近1...
You indicate that the probability of the chi squared test is equal to .000 which you then state "that there's a 0% change to find the observed (or large) degree of association between the variables." This is not exactly correct. The reason the p value is equal .000 is that spss onl...
