\arguments{
\item{dat}{A data frame containing EDA data.}

\item{eda_col}{EDA/conductance column.}

\item{time_col}{Optional time column.}

\item{group_cols}{Optional grouping columns.}

\item{sampling_rate}{Optional sampling rate in Hz. Required if \code{time_col}
does not allow sampling-rate estimation.}

\item{band}{Numeric vector of length two defining the frequency band in Hz.}

\item{min_samples}{Minimum finite samples per group.}

\item{detrend}{Logical. If \code{TRUE}, remove a linear trend before spectral analysis.}

interpretation text.

\description{
Computes power spectral density summaries for an EDA signal, including
spectral power in the EDASymp-inspired 0.045--0.25 Hz band. This is a
descriptive spectral feature and should not be interpreted as direct stress,
emotion, valence, cognition, trust, preference, or diagnosis.
