Declare a governed Gazepoint prediction task

Description

Declare a governed Gazepoint prediction task

Usage

declare_gazepoint_task(
  data,
  outcome,
  purpose,
  task_type = c("classification", "regression"),
  unit_id,
  participant_id = NULL,
  stimulus_id = NULL,
  generalization_target = c("new_trials_known_participants", "new_participants",
    "new_stimuli", "new_participants_and_new_stimuli", "external_validation"),
  positive = NULL,
  observed_outcome = TRUE,
  sensitive_outcome = FALSE
)

Arguments

data	A data frame containing the outcome and task identifiers.
outcome	Name of the explicitly observed outcome column.
purpose	One explicit scientific-purpose statement.
task_type	Either classification or regression.
unit_id	Column identifying the prediction unit.
participant_id	Optional participant-identifier column.
stimulus_id	Optional stimulus-identifier column.
generalization_target	The intended target of generalization.
positive	Positive outcome level for binary classification.
observed_outcome	Whether the outcome was directly observed.
sensitive_outcome	Whether the outcome is sensitive or prohibited.

Value

A governed gp3ml_task object describing the outcome, scientific purpose, prediction unit, grouping roles, task type, and generalization target.

Examples

example_data <- data.frame(
  participant_id = rep(sprintf("P%02d", 1:12), each = 2),
  trial_id = sprintf("T%02d", 1:24),
  stimulus_id = rep(c("S01", "S02"), 12),
  condition = rep(c("A", "B"), 12),
  fixation_duration = 180 + seq_len(24),
  pupil_change = sin(seq_len(24) / 3),
  stringsAsFactors = FALSE
)
