migration.cv.in: In-migration Coefficient of Variation
Description
As "the coefficient of variation is defined as the
standard deviation to mean ratio of a distribution", the
In-migration Coefficient of Variation is computed by
dividing the standard deviation (with the nominator being
\(n\) instead of \(n-1\)) of the in-migration flows
by the mean.
Usage

Arguments
m
migration matrix
Value
A numeric vector of standardized values where a higher
