%description
Implements the Quantile-on-Quantile (QQ) regression methodology developed
by Sim and Zhou (2015) <doi:10.1016/j.jbankfin.2015.01.013>. QQ regression
estimates the effect that quantiles of one variable have on quantiles of
another, capturing the dependence between distributions. The package
provides functions for QQ regression estimation, 3D surface visualization
with 'MATLAB'-style color schemes ('Jet', 'Viridis', 'Plasma'), heatmaps,
contour plots, and quantile correlation analysis. Uses 'quantreg' for
quantile regression and 'plotly' for interactive visualizations.
Particularly useful for examining relationships between financial
variables, oil prices, and stock returns under different market
conditions.
