%description
An implementation of sparsity-ranked lasso for time series data. This
methodology is especially useful for large time series with exogenous
features and/or complex seasonality. Originally described in Peterson and
Cavanaugh (2022) <doi:10.1007/s10182-021-00431-7> in the context of
variable selection with interactions and/or polynomials, ranked sparsity
is a philosophy with methods useful for variable selection in the presence
of prior informational asymmetry. This situation exists for time series
data with complex seasonality, as shown in Peterson and Cavanaugh (2023+)
<doi:10.48550/arXiv.2211.01492>, which also describes this package in
greater detail. The Sparsity-Ranked Lasso (SRL) for Time Series
implemented in 'srlTS' can fit large/complex/high-frequency time series
quickly, even with a high-dimensional exogenous feature set. The SRL is
considerably faster than its competitors, while often producing more
accurate predictions. Also included is a long hourly series of arrivals
into the University of Iowa Emergency Department with concurrent local
temperature.
