gmwm_update_cpp: Update Wrapper for the GMWM Estimator

Description

This function uses information obtained previously (e.g. WV covariance matrix) to re-estimate a different model parameterization

Usage

gmwm_update_cpp(theta, desc, objdesc, model_type, N, expect_diff, ranged, orgV, scales, wv, starting, compute_v, K, H, G, robust, eff)

Arguments

theta
A vec with dimensions N x 1 that contains user-supplied initial values for parameters
desc
A vector indicating the models that should be considered.
objdesc
A field containing a list of parameters (e.g. AR(1) = c(1,1), ARMA(p,q) = c(p,q,1))
model_type
A string that represents the model transformation
scales
A vec that contains the scales or taus (2^(1:J))
starting
A bool that indicates whether we guessed starting (T) or the user supplied estimates (F).
wv_empir
A vec that contains the empirical wavelet variance
omega
A mat that represents the covariance matrix.

Value

A field that contains the parameter estimates from GMWM estimator.
