Simulating Homogenous & Non-Homogenous Poisson Processes
Contains functions and classes for simulating, plotting and analysing homogenous and non-homogenous Poisson processes.
An API Wrapper for 'DAWA' - 'The Danish Address Web API'
Functions for interacting with all sections of the official 'Danish Address Web API' (also known as 'DAWA') < https://api.dataforsyningen.dk>. The development of this package is completely independent from the government agency, Klimadatastyrelsen, who maintains the API.
Flood Frequency Analysis Framework
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)
Interior Point Conic Optimization Solver
A versatile interior point solver that solves linear programs (LPs), quadratic programs (QPs), second-order cone programs (SOCPs), semidefinite programs (SDPs), and problems with exponential and power cone constraints (< https://clarabel.org/stable/>). For quadratic objectives, unlike interior point solvers based on the standard homogeneous self-dual embedding (HSDE) model, Clarabel handles quadratic objective without requiring any epigraphical reformulation of its objective function. It can therefore be significantly faster than other HSDE-based solvers for problems with quadratic objective functions. Infeasible problems are detected using using a homogeneous embedding technique.
Tools for AEMET Climate Data
Download meteorological and climate data from the Spanish Meteorological Agency (AEMET) directly in R using the AEMET API. Create scientific visualizations, including climate charts, climate time series trend analyses, temperature and precipitation anomaly maps, warming stripes and climatograms.
Standard Normal Homogeneity Test
Implementation of robust and non-robust Standard Normal Homogeneity Test (SNHT) for changepoint detection. This test statistic is equal sided, as proposed in "Homogenization of Radiosonde Temperature Time Series Using Innovation Statistics" by Haimberger, L., 2007. However, the statistic contains an estimate of sigma^2 in the denominator instead of sigma, which seems to be a more appropriate value (based on the paper "Homogenization of Swedish temperature data. Part I: Homogeneity test for linear trends." by Alexandersson, H., and A. Moberg, 1997).
Seasonal to Decadal Verification
An advanced version of package 's2dverification'. Intended for
seasonal to decadal (s2d) climate forecast verification, but also applicable
to other types of forecasts or general climate analysis. This package is
specifically designed for comparing experimental and observational datasets.
It provides functionality for data retrieval, post-processing, skill score
computation against observations, and visualization. Compared to
's2dverification', 's2dv' is more compatible with the package 'startR', able
to use multiple cores for computation and handle multi-dimensional arrays
with a higher flexibility. The Climate Data Operators (CDO) version used in
development is 1.9.8. Implements methods described in Wilks (2011)
General Purpose Client for 'ERDDAP™' Servers
General purpose R client for 'ERDDAP™' servers. Includes functions to search for 'datasets', get summary information on 'datasets', and fetch 'datasets', in either 'csv' or 'netCDF' format. 'ERDDAP™' information: < https://upwell.pfeg.noaa.gov/erddap/information.html>.
Tests for Variance Homogeneity
Performs 18 omnibus tests yielding a total of 28 distinct methodological variations for testing the composite hypothesis of variance homogeneity.
Homogeneity of Stratum Effects Test
To test the homogeneity of stratum effects in stratified paired binary data.
