latent_allocation: Finding latent allocation (component indicators) from an angmcmc object

Description

Finding latent allocation (component indicators) from an angmcmc object

Usage

latent_allocation(object, ...)

Value

Returns a vector of length n, where n is the length (if univariate) or number of rows (if bivariate) of the data used in original fit. i-th entry of the output vector provides component label for the i-th data point.

Arguments

object

angular MCMC object.

...

passed to pointest to estimate parameters.

Details

In order to find the latent component indicators, estimates of mixing proportions and model parameters are first computed via pointest. Then, a data point is assigned label j, if the j-th component gives highest density for that point.

Examples

# first fit a vmsin mixture model
# illustration only - more iterations needed for convergence
fit.vmsin.20 <- fit_vmsinmix(tim8, ncomp = 3, n.iter =  20,
                             n.chains = 1)
# now find latent allocation
latent_allocation(fit.vmsin.20)
