Audit session comparability across QC metrics — audit_gazepoint_session

Aggregates selected QC metrics by session, participant, trial, or another grouping unit, then flags unusual values using transparent z-score and/or IQR rules. The function is intended for audit reporting only and does not imply automatic exclusion.

Usage

audit_gazepoint_session_comparability(
  data,
  metric_cols,
  group_cols = NULL,
  method = c("both", "z", "iqr"),
  z_threshold = 2,
  iqr_multiplier = 1.5
)

Arguments

data: A data frame.
metric_cols: Character vector of numeric QC metric columns.
group_cols: Optional character vector defining the session or analysis unit to compare.
method: Outlier rule: "z", "iqr", or "both".
z_threshold: Absolute z-score threshold.
iqr_multiplier: IQR multiplier used for Tukey-style fences.
