Description: A comprehensive toolbox for wavelet-domain quantile
    analyses of bivariate and multivariate time series. Provides Wavelet
    Quantile Regression and Multivariate Wavelet Quantile Regression
    after Adebayo and Ozkan (2024)
    <doi:10.1016/j.jclepro.2024.140832>, Wavelet
    Quantile-on-Quantile regression with bootstrap p-values extending
    Sim and Zhou (2015) <doi:10.1016/j.jbankfin.2015.01.013>, the
    nonparametric Causality-in-Quantiles test of Balcilar, Gupta and
    Pierdzioch (2016) <doi:10.1016/j.resourpol.2016.04.004> together
    with its wavelet variant, Wavelet Quantile Mediation and
    Moderation, Wavelet Quantile Correlation, and a wavelet-based
    nonparametric Quantile Density estimator. The Maximal Overlap
    Discrete Wavelet Transform (MODWT) decomposition is performed via
    'waveslim' and Short / Medium / Long band aggregation is supported
    throughout. For plain Quantile-on-Quantile regression see the
    companion CRAN package 'QuantileOnQuantile'. All interactive 3D
    surfaces, heatmaps and contour plots default to the 'MATLAB'
    'Parula' colour map.
