Initial component allocations for the NMixMCMC function
This is a help function for NMixMCMC function. If
initr is not given, it calculates reasonable initial values for
component allocations. If initr argument is given then it is
checked for consistency and formatted on output.
THIS FUNCTION IS NOT TO BE CALLED BY ORDINARY USERS.
NMixMCMCinitr(z, K, w, mu, Sigma, p, n, initr)
z |
a vector (if p=1) or a n x p matrix with initial values of scaled observations |
K |
a number of mixture components |
w |
a vector with (initial) mixture weights |
mu |
a vector of (initial) mixture means (if p=1) or a K x p matrix with (initial) mixture means in rows (if p>1) |
Sigma |
a vector of (initial) mixture variances (if p=1) or a K*p x p matrix with (initial) mixture covariance matrices put below each other |
p |
dimension of the data |
n |
number of observations |
initr |
a vector of initial component allocations to be checked for consistency. If not given then reasonable initials are generated. |
A vector with reasonable initial component allocations.
