fHMM_data: Constructor of an 'fHMM_data' object

In fHMM: Fitting Hidden Markov Models to Financial Data

Constructor of an fHMM_data object

Description

This function constructs an object of class fHMM_data, which contains the financial data for modeling.

Usage

fHMM_data(
  dates,
  time_points,
  markov_chain,
  data,
  time_series,
  T_star,
  controls,
  true_parameters
)

## S3 method for class 'fHMM_data'
print(x, ...)

## S3 method for class 'fHMM_data'
summary(object, ...)

Arguments

dates	[any] The dates in the empirical case.
time_points	[any] The time points in the simulated case.
markov_chain	[any] The states in the simulated case.
data	[any] The data for modeling.
time_series	[any] The data before transformation.
T_star	[NULL | integer()] The fine-scale chunk sizes.
controls	[fHMM_controls] The fHMM_controls object.
true_parameters	[NULL | fHMM_parameters] The fHMM_parameters object in the simulated case.
x	[fHMM_data] An object of class fHMM_data.
...	Currently not used.
object	[fHMM_data] An object of class fHMM_data.

Value

An object of class fHMM_data, which is a list containing the following elements:

• The matrix of the dates if simulated = FALSE and controls$data$data_column is specified,

• the matrix of the time_points if simulated = TRUE or controls$data$data_column is not specified,

• the matrix of the simulated markov_chain if simulated = TRUE,

• the matrix of the simulated or empirical data used for estimation,

• the matrix time_series of empirical data before the transformation to log-returns if simulated = FALSE,

• the vector of fine-scale chunk sizes T_star if controls$hierarchy = TRUE,

• the input controls,

• the true_parameters.
