what confidence interval is used to select a factor which variable to select in a lmer how to select iv factor in linear mixed model which intervals are important for the selection of factors can iv be selected from finite value in lmer can you select iv from t value when selecting a factor the confidence interval is why is the t value important for linear mixed model can you select factors from confidence interval for lmer how to select the factors in lmer can you select the iv factor can iv be selected by a confidence interval what range of confidence intervals to select factor in lmer how to select the variables in a mixed model how to select variables using confidence interval how does iv affect confidence intervals if the t value of lmer is positive or negative, can we select the factors of the fixed effect? which factor in an lmer is selected from the t value? what is the confidence interval for lmer can iv select from the confidence interval
