Linear Dynamical System Reconstruction
Streamflow (and climate) reconstruction using Linear Dynamical Systems.
The advantage of this method is the additional state trajectory which can reveal more information
about the catchment or climate system. For details of the method please refer to Nguyen and Galelli
(2018)
Self Organising Maps for the Analysis of Molecular Dynamics Data
Processes data from Molecular Dynamics simulations using
Self Organising Maps. Features include the ability to read different
input formats. Trajectories can be analysed to identify groups of important
frames. Output visualisation can be generated for maps and pathways.
Methodological details can be found in Motta S et al (2022)
Develop a 'Telegram Bot' with R
Provides a pure interface for the 'Telegram Bot API' < http://core.telegram.org/bots/api>. In addition to the pure API implementation, it features a number of tools to make the development of 'Telegram' bots with R easy and straightforward, providing an easy-to-use interface that takes some work off the programmer.
Extra Functionality for 'leaflet' Package
The 'leaflet' JavaScript library provides many plugins some of which are available in the core 'leaflet' package, but there are many more. It is not possible to support them all in the core 'leaflet' package. This package serves as an add-on to the 'leaflet' package by providing extra functionality via 'leaflet' plugins.
Create Interactive Web Maps Using 'The National Map' Services
Creates interactive web maps using the 'JavaScript' 'Leaflet' library with base layers of 'The National Map' ('TNM'). 'TNM' services provide access to base geospatial information that describes the landscape of the United States and its territories. This package is dependent on, and intended to be used with, the 'leaflet' package.
Lagged Weighted Quantile Sum Regression
Wrapper functions for the implementation of lagged weighted
quantile sum regression, as per 'Gennings et al' (2020)
Tools for Analysis, Design, and Operation of Water Supply Storages
Measure single-storage water supply system performance using resilience, reliability, and vulnerability metrics; assess storage-yield-reliability relationships; determine no-fail storage with sequent peak analysis; optimize release decisions for water supply, hydropower, and multi-objective reservoirs using deterministic and stochastic dynamic programming; generate inflow replicates using parametric and non-parametric models; evaluate inflow persistence using the Hurst coefficient.
A Modification of Fleiss' Kappa in Case of Nominal and Ordinal Variables
The kappa statistic implemented by Fleiss is a very popular index for assessing the reliability of agreement among multiple observers. It is used both in the psychological and in the psychiatric field. Other fields of application are typically medicine, biology and engineering. Unfortunately,the kappa statistic may behave inconsistently in case of strong agreement between raters, since this index assumes lower values than it would have been expected. We propose a modification kappa implemented by Fleiss in case of nominal and ordinal variables. Monte Carlo simulations are used both to testing statistical hypotheses and to calculating percentile bootstrap confidence intervals based on proposed statistic in case of nominal and ordinal data.
Multivariate Model Based Inference for Domains
Allows users to produce estimates and MSE for multivariate variables using Linear Mixed Model. The package follows the approach of Datta, Day and Basawa (1999)
Helper Functions for Bayesian Analyses
Functions to 'numericise' 'R' objects (coerce to numeric objects), summarise 'MCMC' (Monte Carlo Markov Chain) samples and calculate deviance residuals as well as 'R' translations of some 'BUGS' (Bayesian Using Gibbs Sampling), 'JAGS' (Just Another Gibbs Sampler), 'STAN' and 'TMB' (Template Model Builder) functions.
