generation.alpha.3strains: Generation of parameters for the simulations under the regression model
Description
Generation of parameters of the Dirichlet distribution used to draw the proportions of three strains at each site given in a matrix of coordinates.
Usage
generation.alpha.3strains(x)
Arguments
x
[2-column matrix] Coordinates where Dirichlet parameters are drawn.
Value
Matrix of positive numerics with three columns corresponding to the number of strains that are considered and with number of rows equal to the number of sites given in x. Each row of the matrix provides the parameters of the Dirichlet distribution used to draw the proportions of three strains at each site given in x.
