calc_non_I_set {thamesmix} | R Documentation |
Calculates the set I(G) described in Metodiev et al. (2025) as well as the limit on the complexity of the THAMES associated with it.
Description
Calculates the set I(G) described in Metodiev et al. (2025) as well as the limit on the complexity of the THAMES associated with it.
Usage
calc_non_I_set(scaling, G, sims, c_opt)
Arguments
scaling |
list of fit determined via QDA (means and covariances) |
G |
number of components |
sims |
n_simul x G x (u+1) array of parameters sampled from the posterior, where n_simul is the number of simulations from the posterior, G is the number of components, u is the number of mixture component parameters (parameter u+1 is the mixture weight) |
c_opt |
radius of the ellipsoid E from Metodiev et al. (2025) |
Value
a named list with the following elements: graph: the overlap graph for G non_I_set: the complement of the set I(G) complexity_limit_estim: an upper bound on the THAMES complexity graphmat: adjacency matrix of the overlap graph for G
