Generate a pseudo predator parametrically from multivariate normal distributions.
pseudo.pred.norm(mu.mat, sigma.pool, diet)A simulated predator FA signature. See pseudo.pred for an example illustrating how to generate a sample of pseudo predators.
matrix where each row represents the mean transformed FA signature of each prey type
pooled variance-covariance matrix of the transformed fatty acid signatures of prey types
the "true" or "desired" diet of the pseudo predator with prey species in the same order as the rows of mu.mat. A compositional vector of proportions that sums to one with length equal to the number of prey species.
Similar to pseudo.pred but instead generates the pseudo-predators parametrically by assuming ilr transformed FA signatures have a multivariate normal distribution.
