plot_accuracy_ddm: Plot accuracy for DDM model (internal)

In eam: Evidence Accumulation Models

Plot accuracy for DDM model (internal)

Description

Calculates hit rate (proportion of trials with choice == 1) across all possible trial combinations. For simulated data, expands grid based on simulation config parameters and left joins with actual simulation results. For observed data, assumes data is already in the correct format.

Usage

plot_accuracy_ddm(
  simulated_output,
  observed_df,
  x = "item_idx",
  facet_x = c(),
  facet_y = c()
)

Arguments

simulated_output	Simulation output object
observed_df	Observed data frame (already expanded with all trial combinations)
x	Variable for x-axis
facet_x	Variables for faceting columns
facet_y	Variables for faceting rows

Value

A ggplot2 object
