subroutine.`pooled.sd(x, block)`

x

`numeric`

`vector`

or `matrix`

with variables in columns.block

`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 standard deviation.

`block`

describes a unique sample group, ordinary sample standard deviation will be computed.- Dazard J-E., Hua Xu and J. S. Rao (2011). "
