用sas做了logistic回归但结果和spss、R不一致?spss和R结果week0-group的估计值为-0.695 sas的结果为-0.347但是两者的p值是差不多的其他连续型变量的结果都差不多不知道为什么只有week0-group这个分类变量的估计值不一致原始数据在附件
sas代码proc logistic data=a2;class  record_id week0_group(REF=first) ;model respo_rate_6= week0_group meam_liquid_stool_count week1s_abdomen_pain_avg/cl rl lackfit;run;R语言代码glm4<-glm(respo_rate_6~meam_liquid_stool_count+week1s_abdomen_pain_avg+week0_group,family=binomial(link="logit"),data=data_3)
