altimDSWE and RSQcomp R Packages For Remote Sensing Discharge altimDSWE and RSQcomp R Packages For Remote Sensing Discharge
Projects and apps to support computation of stream discharge using remotely-sensed satellite data. (RSQ, Remotely Sensed Discharge): altimDSWE: Shiny app tool to support development of relations between satellite altimetry and DSWE data RSQcomp: Shiny app tool for computing stream discharge using remotely sensed data
A comparison of statistical modeling approaches for hierarchical data: A simulation study and application to ecology data A comparison of statistical modeling approaches for hierarchical data: A simulation study and application to ecology data
The repository contains code to analyze the differences in model results when nested design structures differ. The code for this project assumes the reader is familiar with R, nested designs, and mixed effects linear modeling.
occStan: Occupancy models with RStan occStan: Occupancy models with RStan
occStan is an R package (R Core Team 2021) providing a collection of occpuancy Bayesian models written in the Stan language as called through RStan (Stan Development Team 2021). The package is a USGS software software release. The purpose of the package is to document these models for use in USGS projects and allow easy discrimination. The package assumes the user is familiar with R and...

STEPS: Slip Time Earthquake Path Simulations applied to the San Andreas and Toe Jam Hill faults to redefine geologic slip rate uncertainty (Matlab code) STEPS: Slip Time Earthquake Path Simulations applied to the San Andreas and Toe Jam Hill faults to redefine geologic slip rate uncertainty (Matlab code)
Geologic slip rates are a time-averaged measurement of fault displacement calculated over 100s- to 1,000,000-year time scales and are a primary input for probabilistic seismic hazard analyses (PSHA), which forecast expected ground shaking in future earthquakes. Despite their utility for seismic hazard calculations, longer-term geologic slip rates represent a time-averaged measure of the...
