卡方检验有很多种,特别是在医学数据处理中,不同的卡方反应的意义是不同的,比如pearson卡方,似然比卡方。。。,有哪位高手可以总结一下。最好能举例说明一下,以便大家共同学习

in some sense, they are both likelihood ratio tests.
tests are determined by the test function, instead of the null distribution.
although it might be reasonable to "try" to give a general formulation of the test functions to the tests with the same asymptotic null distribution, it makes no sense in general to conclude so.

讲的比较深奥,可否举个例子,从实际意义上讲一下,不如,是构成比的检验,还是率的检验,还是行平均分的检验,这些检验和一般统计模型中的检验又有什么区别。
不好意思呀,统计基本功太差,呵呵
