Function to choose method for Weighted Quantile Regression


Weight the data and then call the chosen fitting algorithm.


rq.wfit(x, y, tau=0.5, weights, method="br", ...)


x the design matrix
y the response variable
tau the quantile desired, if tau lies outside (0,1) the whole process is estimated.
weights weights used in the fitting
method method of computation: "br" is Barrodale and Roberts exterior point "fn" is the Frisch-Newton interior point method.
