| Abstract: | This paper rEanalysEs the data about therapeutic effect of stomach trouble by log-linear model. Original results showed that drug age and symptom affect the therapeutic result, but didn't occur interaction between every two variables; that is, no matter what the age was, young or old, and no matter what symptom was, mild or serious, the therapeutic effect of drugs is the same. Using log-linear model, we found that therapeutic effect only related with ages and symptomes: under 39 years old, therapy has no effect, its slandardized parameter is -1273 7; standardized parameters of 3 levels of symptom arc among 0.879 7, 1074 6 and -1954 3, respectively, that means that has no dear trend for light, remarkable effect for medium, but no effect for weight From that data, we can't obtain enough evidence that experimental drug have effect for stomach trouble. |
