set_agg_data: Set aggregated data to a model object

In dRiftDM: Estimating (Time-Dependent) Drift Diffusion Models

Set aggregated data to a model object

Description

Helper function that aggregates a data set across all participants and attaches the resulting group-level summary statistics to a drift_dm_obj. This is required when the user wants to fit aggregated data (e.g., via the RMSE cost function).

Usage

set_agg_data(drift_dm_obj, obs_data_ids, ...)

Arguments

drift_dm_obj	a model object (of class drift_dm) to which the aggregated data will be attached.
obs_data_ids	a data.frame containing individual-level observations. Must include an ID column identifying participants.
...	optional arguments (currently supported are n_bins and probs which are relevant when using the rmse cost function)

Details

This function is intended for internal use and is called by estimate_dm() when aggregated model fitting is requested.

Value

The updated drift_dm_obj with aggregated stats_agg and obs_data set to NULL.
