在spss中,logistics回归中,有专门的选项来处理需要哑变量化的变量,只需单击“Categorical..”进行设置即可。但是对于多元线性回归就没有那么幸运了。 用computer或recode设置一组哑变量。由于哑变量是一个整体变量,所以进行变量筛选时必须共同进退。因此,讲所有哑变量同一般变量一下直接进行筛选是不对的,会出现一部分变...
Chi-SquareWe use chi square goodness of fit to assess if frequencies of a categorical variable were likely to happen due to chance. Use of a chi square test is necessary whether proportions of a categorical variable are a hypothesized value.PROC FREQ ...
在第四章我们看到了判断一个continuous reponse variable是否依赖于几个categorical variables。 对于Balanced dataset可以用Anova model。 但是proc Anova对于unbalanced dataset不成立。(unbalanced data就是指每个…阅读全文 赞同3 1 条评论 分享收藏 SAS第六七章 第六章简单线性回归 第六章就是...
Multiple methods are available in SAS to evaluate trends of continuous and categorical variables using PROC REG (simple linear regression) and PROC FREQ (Jonckheere-Terpstra, CochranArmitage and Cochran-Mantel-Haenszel tests) statements. However, choosing the appropriate statistical test can be a ...

ANOVA It is also used to compare means when there is one independent categorical variable. We want to use one-way ANOVA when testing to see if the means of the interval dependent variable are different according to the independent categorical variable. PROC ANOVA Chi-Square We use chi square ...
This article demonstrates how to use PROC GENMOD to perform a Poisson regression in SAS. There are different examples in the SAS documentation and in conference papers, but I chose this example because it uses two categorical explanatory variables. Therefore, the Poisson regression can be visualized...
