qdks: A quick and dirty non-parametric quantile estimator based on...

In waternumbers/FloodForT: Flood Forecasting Toolbox

Description

This function runs a estimator of the quantiles of y depending upon x. It pools the values of y into bins based on the quantiles of x then interpolates in a linear fashion assuming the quantiles occur at the bin centre. Out of range extrapolation depends upon rule - see approx function in the stats package

Usage

qdks(y, x, q = seq(5, 95, 5)/100, xout = NA, rule = 2)

Arguments

y	Values whose quantiles are sought
x	Explanatory variable
q	Quantiles estimated. Default is 0.05,0.1,...,0.95
xout	Value of x to return quantiles at. NA (default) returns values for seq(min(x),max(x),length=100)
rule	See approx function in stats. default is 2, take closest end point
