%description
Detrending multivariate time-series to approximate stationarity when
dealing with intensive longitudinal data, prior to Vector Autoregressive
(VAR) or multilevel-VAR estimation. Classical VAR assumes weak
stationarity (constant first two moments), and deterministic trends
inflate spurious autocorrelation, biasing Granger-causality and
impulse-response analyses. All functions operate on raw panel data and
write detrended columns back to the data set, but differ in the level at
which the trend is estimated. See, for instance, Wang & Maxwell (2015)
