我正在尝试使用lmer()构建一个线性混合效果模型,但输出我只是看起来像这样

> model <- lmer(elogit_ToTarget ~ (Age..vA..months. + EVT_GSV + DDNotAgeSensitive)*(OrthTime + OrthTime2) +
+                 ( OrthTime + OrthTime2 | Subject ), data=d)
> print(model, correlation=F)
Linear mixed model fit by REML ['lmerMod']
Formula: elogit_ToTarget ~ (Age..vA..months. + EVT_GSV + DDNotAgeSensitive) *  
    (OrthTime + OrthTime2) + (OrthTime + OrthTime2 | Subject)
   Data: d
REML criterion at convergence: 373.2443

在我看过的其他示例中,除了估算之外,还有标准错误和t值的列,但这似乎不是可以指定的选项。我怎么能得到这些?

使用summary(model);如果要提取固定效果系数表,请使用coef(summary(model))
