JLL: Estimates the P-dynamics from JLL-based models

Description

Estimates the P-dynamics from JLL-based models

Usage

JLL(NonOrthoFactors, N, JLLinputs, CheckInputs = FALSE)

Value

List of model parameters from both the orthogonalized and non-orthogonalized versions of the JLL's based models

Arguments

NonOrthoFactors

A numeric matrix (F x T) representing the time series of risk factors before the orthogonalization process.

N

Integer. Number of country-specific spanned factors.

JLLinputs

List of necessary inputs to estimate JLL models:

1. Economies: set of economies that are part of the economic system (string-vector)

2. DomUnit: A string specifying the name of the economy assigned as the dominant unit.
   If no dominant unit is assigned, set this variable to "None".

3. WishSigmas: Set to "1" if the user wishes to estimate the variance-covariance matrices and Cholesky factorizations
   (this can take a long time). Set to "0" if not.

4. SigmaNonOrtho: A NULL value or an F x F matrix from the non-orthogonalized dynamics.

5. JLLModelType: A string specifying the type of JLL model. Available options are: "JLL original", "JLL joint Sigma", or "JLL No DomUnit".

CheckInputs

A logical flag to indicate whether to perform a prior consistency check on the inputs provided in JLLinputs. The default is set to FALSE
