%description
Owing to the rich shapes of Generalised Lambda Distributions (GLDs), GLD
standard/quantile/Accelerated Failure Time (AFT) regression is a
competitive flexible model compared to standard/quantile/AFT regression.
The proposed method has some major advantages: 1) it provides a reference
line which is very robust to outliers with the attractive property of zero
mean residuals and 2) it gives a unified, elegant quantile regression
model from the reference line with smooth regression coefficients across
different quantiles. For AFT model, it also eliminates the needs to try
several different AFT models, owing to the flexible shapes of GLD. The
goodness of fit of the proposed model can be assessed via QQ plots and
Kolmogorov-Smirnov tests and data driven smooth test, to ensure the
appropriateness of the statistical inference under consideration.
Statistical distributions of coefficients of the GLD regression line are
obtained using simulation, and interval estimates are obtained directly
from simulated data.  References include the following: Su (2015)
