Prior to posterior updating for a multivariate normal mixture

Calculate conjugate posterior mixture of multivariate normals with known covariance matrix

Usage

mvpostmix(priormix, mu_hat, S_hat)

priormix: Prior multivariate normal mixture given as a list of length 3. The first list entry contains the mixture weights, the second component the mean vectors and the third component of the list the covariance matrices.
mu_hat: estimated mean response for each dose
S_hat: estimated covariance matrix

Returns a posterior multivariate normal mixture as a list of length 3, containing mixture weights, mean vectors and covariance matrices.
