如果因子变量包含非整数值或超出指定范围的整数值,Stata将无法正确解析这些值,从而引发错误。 3. 解决“factor variables may not contain noninteger values”错误的方法 要解决这个问题,你需要确保因子变量中的值都是非负整数,并且在指定的范围内。以下是几种可能的解决方案: 转换变量类型:如果变量原本是
Factor variables Order <- See Stata's other features Stata handles factor (categorical) variables elegantly. You can prefix a variable withi.to specify indicators for each level (category) of the variable. You can put a#between two variables to create an interaction–indicators for each ...

否则,如果直接i.xingbie放入回归,Stata是会报错的。 . reg income i.xingbie //Stata报错 xingbie: string variables may not be used as factor variables r(109); . xi: reg income i.xingbie //xingbie,是一个字符型的分类变量 i.xingbie _Ixingbie_1-2 (_Ixingbie_1 for xingbie==女 omitted...
对于第一种方法,也就是如果我直接:xtologit y x1 x2 i.year i.industry i.id ,会出现报错“id: factor variables may not contain noninteger values”; 第二种方法,也就是输入xtologit y x1 x2 i.year i.industry,vce(cluster id),stata不会报错,但不知道这样处理对不对。
The prognostic variables were categorised, and the prediction table of the not-localised prostate cancer probability was developed from them. Clinical stage, prostatic specific antigen and Gleason's "grade" were identified as prognostic factors, taking into account that the higher they are, the ...

the current estimation results for cox have 4 equations so you mustspecify 4 new variables, or you can use the equation() option and specify one variable at a time r(102); If I use the preexisting indicators wbc2 and wbc3 (as in the examplein the manual) instead of the factor variab...
