Which is linear mixed effect model fits the LME?
This generic function fits a linear mixed-effects model in the formulation described in Laird and Ware (1982) but allowing for nested random effects. The within-group errors are allowed to be correlated and/or have unequal variances. The methods lme.lmList and lme.groupedData are documented separately.
When does version 3 of nlme come out?
Package ‘nlme’. August 1, 2019. Version 3.1-141 Date 2019-08-01 Priority recommended Title Linear and Nonlinear Mixed Effects Models Description Fit and compare Gaussian linear and nonlinear mixed-effects models.
Is the default correlation of nlme : LME null?
I just noticed that the default correlation of nlme::lme () is NULL. The explanation of argument for correlation is correlation: Defaults to NULL, corresponding to no within-group correlations.
How are are and LME used in longitudinal analysis?

What is an object of class ” LME “?
An object of class “lme” representing the linear mixed-effects model fit. Generic functions such as print, plot and summary have methods to show the results of the fit. See lmeObject for the components of the fit.
What happens when the data contain NAS in LME?
a function that indicates what should happen when the data contain NAs. The default action (na.fail) causes lme to print an error message and terminate if there are any incomplete observations.
What does the default action do in LME?
The default action ( na.fail) causes lme to print an error message and terminate if there are any incomplete observations. a list of control values for the estimation algorithm to replace the default values returned by the function lmeControl . Defaults to an empty list.
