atCfn: Calculate corrected temporal mean coefficients of selection

Description

Calculate the temporal mean coefficients of selection (alpha) corrected for sampling error, i.e. the best linear predictor (BLP) of alpha.

Usage

atCfn(aM, M, At, at)

Arguments

aM

the estimated temporal mean selection coefficients.

M

the estimated temporal covariance matrix (fluctuating selection).

At

a list containing the named variance-covariance matrix for each year. Sorted by year.

at

a list containing the named vectors of the estimated selection coefficient for each year. Sorted by year.

Value

Returns a vector with the named best linear predictors for the temporal mean coefficients of selection (alpha).

Details

Further details are found in Engen et al. 2012.
