getObjFunStarting: Retrieve GMWM starting value from Yannick's objective function

Description

Obtains the GMWM starting value given by Yannick's objective function optimization

Usage

getObjFunStarting(theta, desc, objdesc, model_type, wv_empir, tau)

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 containing the model type. Either 'imu' or 'ssm'
wv_empir
A vec containing the empirical wavelet variance.
tau
A vec that contains the scales of 2^(1:J), where J is the number of scales created by the decomposition.

Value

A double that is the value of the Objective function under Yannick's starting algorithm
