Variance of genealogical depth

Share:

Description

Returns the variance of the genealogical depth

Usage

1
gen.meangendepthVar( gen, pro = "0", type = "MEAN", ...)

Arguments

gen

An object of class GLgen obtained with gen.genealogy, gen.lineages or gen.branching. Required.

pro

Vector of proband id numbers to be included. Default is 0, which will select all individuals without children.

type

If type="MEAN" (default), the average of genealogical depth variances (over all probands) is returned. If type="IND", the variance of the genealogical depth is calculated for each specified proband.

...

Option to pass additionnal arguments automaticaly between methods. Internal use only.

Value

A data frame with only one numeric value when type is "MEAN". When type is "IND", the number of rows equals the number of probands specified.
