Audit pupil-luminance confounding — audit_gazepoint_pupil_luminance • gpbiometrics

Computes correlations between pupil size and luminance/brightness and flags groups where the absolute association exceeds a threshold.

Usage

audit_gazepoint_pupil_luminance(
  data,
  pupil_col = NULL,
  luminance_col = NULL,
  group_cols = NULL,
  threshold = 0.3,
  method = c("pearson", "spearman")
)

Arguments

data: Data frame containing pupil and luminance columns.
pupil_col: Pupil column.
luminance_col: Luminance/brightness column.
group_cols: Optional grouping columns.
threshold: Absolute correlation threshold for flagging.
method: Correlation method.

Value

Data frame with correlation and flag columns.
