Constructor for the `EnsembleData` class

Description

A constructor for the EnsembleData class. This is used to convert input data into the required form for fit_ensemble_model.

Usage

EnsembleData(observations, simulators, priors, drivers = FALSE, MMod)

Arguments

`observations`	A `list` of length 2 containing observations and a covariance matrix. The first element is a `data.frame` or `matrix` with each column giving observations of each output of interest and each row a time. Rows should be named with the times and columns should be named the variables. The second element is is a `d \times d` `matrix` where `d` is the number of columns of the observations data frame / matrix. This matrix is the covariance matrix of the observations.
`simulators`	A `list` with length equal to the number of simulators. For each simulator, there is a `list` of 2 objects containing the simulator output and covariance matrix. The first element is a `data.frame` or `matrix` with each column giving a simulator outputs of interest and each row a time. Rows should be named with the times and columns should be named the variables. The second element is a `n_k \times n_k` `matrix` where `n_k` is the number of columns of the simulators output data frame / matrix. This matrix is the covariance matrix of the simulator outputs.
`priors`	An `EnsemblePrior` object specifying the prior distributions for the ensemble.
`drivers`	A `logical` indicating whether drivers have been used in combination with simulators. Default value is FALSE.
`MMod`	Not currently implemented.

Value

An object of class EnsembleData

Examples

ensemble_data <- EnsembleData(observations = list(SSB_obs, Sigma_obs),
                             simulators = list(list(SSB_ewe, Sigma_ewe, "EwE"),
                                           list(SSB_fs,  Sigma_fs, "FishSUMS"),
                                           list(SSB_lm,  Sigma_lm, "LeMans"),
                                           list(SSB_miz, Sigma_miz, "mizer")),
                              priors = EnsemblePrior(4))
