kinshipShift R Documentation
Shifts a kinship matrix
Description
Shifts a kinship matrix
Usage
kinshipShift(x,shift=NULL)
Arguments
x
a square matrix
shift
the amount by which the elements of x should be shifted. if shift==NULL,
the average of the off-diagonal elements is substracted
Details
The kinship matrix produced by beta.dosage is relative to the average kinship
of the set of individuals analysed (1/(n(n-1)/2) ∑_i ∑_{j>i} x_{ij}=0).
Another reference point might be useful, for instance to avoid negative kinship values, one might
want to shift the matrix by min(x_{ij}), i \neq j.
Value
the shifted kinship matrix \frac{x-shift}{1-shift}
