update_stats_agg: Update aggregated statistics in a 'drift_dm' object

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

Update aggregated statistics in a drift_dm object

Description

Internal function that creates or updates the aggregated statistics (stats_agg and stats_agg_info) in a drift_dm object, depending on the specified cost function. For maximum likelihood estimation ("neg_log_like"), aggregated statistics are removed, because the raw RTs are used directly.

Usage

update_stats_agg(
  drift_dm_obj,
  which_cost_function,
  probs = NULL,
  n_bins = NULL
)

Arguments

drift_dm_obj	a drift_dm object.
which_cost_function	a character string, indicating which cost function is used. Must be one of drift_dm_cost_functions().
probs	optional numeric vector of probabilities for quantile calculation. If NULL, defaults are taken from drift_dm_default_probs().
n_bins	an optional integer, giving the number of bins for the CAFs. If NULL, defaults are taken from drift_dm_default_n_bins().

Value

the input drift_dm_obj, with its stats_agg and stats_agg_info entries updated or removed, depending on the cost function and availability of observed data

Note

This function is called by obs_data() and cost_function()
