Build an empirical bivariate calibration-error model

Build an empirical bivariate calibration-error model

Usage

calibration_error_model(
  data,
  gaze_x = "gaze_x",
  gaze_y = "gaze_y",
  target_x = "target_x",
  target_y = "target_y"
)

Arguments

data

Validation-target data.

gaze_x, gaze_y

Recorded gaze-coordinate columns.

target_x, target_y

Known target-coordinate columns.

Value

An object of class "eye_calibration_error_model", stored as a named list, with components "mean_error", "covariance", "errors", "n", "metrics", "coordinate_units", "status", "caveat". It contains an empirical bivariate calibration-error model and associated metadata or diagnostics needed to interpret the result.
