rjaneUCF/MultiHazard: Tools for modeling compound events

This package provides tools for stationary multivariate statistical modeling. For instance to model the joint distribution of co-occurring hazards. The package contains functions for pre-processing data including imputing missing values, detrending and declustering time series as well as analyzing pairwise correlations over a range of lags. Functionality is also built in to conditionally sample a bivariate dataset (given one of the variables is above a predetermined threshold) and select the best fitting amongst an array of parametric (extreme and non-extreme, truncated and non-truncated) marginal distributions or copulas. Estimation of joint probability contours using the method of overlaying (conditional) contours given in Bender et al. (2016) and subsequently for a given return period extracting design events assuming full dependence, as well as the "most likely" or an ensemble of possible design events once accounting for dependence is possible. The package also provides the capability of fitting and simulating synthetic records from three higher dimensional approaches - standard (elliptic/Archimedean) copulas, Pair Copula Constructions (PCCs) and the conditional threshold exceedance approach of Heffernan and Tawn (2004). The package provides the code and data used in Jane et al. (2020), consequently applications in this vignette center around assessing the potential for compound flooding in South Florida.
