mal.cond: Calculates a Conditional Kinship matrix

Description

The function ``mal.cond'' calculates a R conditional kinship matrix starting from a kinship matrix obtained by the applicatio of the Malecot migration model on a colum stochastic migration matrix.

Usage

mal.cond(PHI, N)

Arguments

PHI

PHI is a square and symmetrical kinship matrix, possibly the output of the function Phi

N

N is the effectiove population vector

Value

Returns a square symmetrical matrix.

Details

Much more useful than the Phi matrix, the conditional kinship R matrix is the basis for further analysis by means of Mantel tests, Procrustes rotations and cluster analysis.
