param-ns-structure

internal

Tools to support systematic and reproducible workflows for both
stationary and nonstationary flood frequency analysis, with applications
extending to other hydroclimate extremes, such as precipitation frequency
analysis. This package implements the FFA framework proposed by Vidrio-
Sahagún et al. (2024) <doi:10.1016/j.envsoft.2024.105940>, originally
developed in MATLAB, now adapted for the R environment. This work was
funded by the Flood Hazard Identification and Mapping Program of Environment
and Climate Change Canada, as well as the Canada Research Chair (Tier 1)
awarded to Dr. Pietroniro.

param-ns-structure function

<dl><dt>ns_structure</dt>
<dd>For NS-FFA only: Named list indicating which distribution
parameters are modeled as nonstationary. Must contain two logical scalars:<ul>
<li><code>location</code>: If <code>TRUE</code>, the location parameter has a linear temporal trend.</li>
<li><code>scale</code>: If <code>TRUE</code>, the scale parameter has a linear temporal trend.</li>
</ul></dd></dl>
