This function calculates the relative variance change (RVC) of
hierarchical linear models fit via lmer
.
## Default S3 method:
rvc(model, ...)
## S3 method for class 'mer'
rvc(model, level = 1, delete = NULL, ...)
## S3 method for class 'lmerMod'
rvc(model, level = 1, delete = NULL, ...)
## S3 method for class 'lme'
rvc(model, level = 1, delete = NULL, ...)
model |
fitted model object of class |

level |
variable used to define the group for which cases will be
deleted. If |
delete |
index of individual cases to be deleted. To delete specific
observations the row number must be specified. To delete higher level
units the group ID and |
If delete = NULL
a matrix with columns corresponding to the variance
components of the model and rows corresponding to the deleted
observation/group is returned.
If delete
is specified then a named vector is returned.
The residual variance is named sigma2
and the other variance
components are named D**
where the trailing digits give the
position in the covariance matrix of the random effects.
