MVR (version 1.20.0)

pooled.mean: Pooled Group Sample Mean Subroutine


Internal subroutine called by end-user function mvr and internally by MeanVarReg subroutine.


pooled.mean(x, block)


numeric vector or matrix with variables in columns.
vector or factor grouping/blocking variable. Must Have length equal to the sample size. All group sample sizes must be greater than 1.


  • numeric vector of size the dimensionality where each entry is the variable-wise pooled group sample mean.


If block describes a unique sample group, ordinary sample mean will be computed.
