Cumulative distribution function (cdf) for fitted distance sampling detection function

Computes cdf values of observed distances from fitted distribution. For a set of observed x it returns the integral of f(x) for the range= (inner, x), where inner is the innermost distance which is observable (either 0 or left if left truncated). In terms of g(x) this is the integral of g(x) over range divided by the integral of g(x) over the entire range of the data (inner, W).

Usage

cdf.ds(model, newdata = NULL)

Arguments

model

fitted distance sampling model

newdata

new data values if computed for values other than the original observations

Value

vector of cdf values for each observation

Note

This is an internal function that is not intended to be invoked directly. It is called by qqplot.ddf to compute values for Kolmogorov-Smirnov and Cramer-von Mises tests and the Q-Q plot.
