%description
Enable users to evaluate long-term trends using a Generalized Additive
Modeling (GAM) approach. The model development includes selecting a GAM
structure to describe nonlinear seasonally-varying changes over time,
incorporation of hydrologic variability via either a river flow or
salinity, the use of an intervention to deal with method or laboratory
changes suspected to impact data values, and representation of left- and
interval-censored data. The approach has been applied to water quality
data in the Chesapeake Bay, a major estuary on the east coast of the
United States to provide insights to a range of management- and
research-focused questions.  Methodology described in Murphy (2019)
<doi:10.1016/j.envsoft.2019.03.027>.
