Flag EDA artifacts using transparent Kleckner-style heuristics — flag_kleckner_eda

Applies simple transparent EDA artifact flags: non-finite values, physiological range violations, rapid percent change per second, and transitional padding around flagged samples.

Usage

flag_kleckner_eda_artifacts(
  dat,
  eda_col = "GSR_US",
  time_col = NULL,
  group_cols = NULL,
  min_us = 0.01,
  max_us = 100,
  max_abs_percent_change_per_second = 20,
  transition_padding = 1,
  output_prefix = "kleckner"
)

Arguments

dat: A data frame containing EDA data.
eda_col: Conductance column in microsiemens.
time_col: Optional time column.
group_cols: Optional grouping columns.
min_us: Minimum plausible conductance.
max_us: Maximum plausible conductance.
max_abs_percent_change_per_second: Maximum absolute percent change per second before flagging.
transition_padding: Number of neighbouring rows to flag around bad samples within each group.
output_prefix: Prefix for output columns.

Value

A data frame with artifact flag columns and summary attributes.

Details

This helper is Kleckner-style rather than a claim of exact reproduction of every rule in a specific external implementation.
