mal.cond: Calculates a Conditional Kinship matrix

In Biodem: Biodemography Functions

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

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.

Value

Returns a square symmetrical matrix.
