跑来请教各位学统计的大牛！！！先谢过 ：）
Now I have 1500 patients associated with 4 diseases，with each patient only diagnosed with one disease;
my observed results are
total: 1500 (number of people)
disease 1: 600 (number of people diagnosed with disease 1)
disease 2: 320
disease 3: 380
disease 4: 200
my expected results are
total: 1500 (number of people)
disease 1: 250 (number of people diagnosed with disease 1)
disease 2: 250
disease 3: 400
disease 4: 600
Based on previous studies, t |

我查了下
第一个和第二个test的pValue都很小，接近于0
不过第一个test的x^2结果比第二个大很多
the first test: x^2 = 586.3212
the second test: x^2 = 23.1852
不知道这样是不是也可以作为stronger evidence?
多谢大侠指点 =D
