P values in lmer
WebWhile assuming the model is correct regarding all assumptions, then anova function in lmerTest package will give us exact p-values for testing fixed effects. The parametric booktstrap method is mainly used for testing the random effects if you want to obtain a less conservative p-values of exact likelihood ratio tests (LRTs) than those of the ... WebWith lmer, I used the emmeans package to determine differences between the two groups at each time point. But this uses the estimated marginal means rather than the observed values and so the determined p-values seem to be affected by the amount of missing data points at each time point.

WebKey Results: P-Values. Variety is the fixed factor term, and the p-value for the variety term is less than 0.000. Because this value is less than 0.05, you can conclude that the level means are not all equal, meaning the variety of alfalfa has an effect on the yield. To obtain a better understanding of the main effects, go to Factorial Plots. WebThe model_parameters() function also allows the computation of standard errors, confidence intervals, and p-values based on various covariance matrices: heteroskedasticity-consistent, cluster-robust, bootstrap, etc.This functionality relies on the sandwich and clubSandwich packages.
