qtable: Interpolate tabularized distribution

In outliers: Tests for Outliers

Interpolate tabularized distribution

Description

This function calculates critical values or p-values which cannot be obtained numerically, and only tabularized version is available.

Usage

qtable(p, probs, quants)

Arguments

p	vector of probabilities.
probs	vector of given probabilities.
quants	vector of given corresponding quantiles.

Details

This function is internal routine used to obtain Grubbs and Dixon critical values. It fits linear or cubical regression to closests values of its argument, then uses obtained function to obtain quantile by interpolation.

Value

A vector of interpolated values

Note

You can simply do "reverse" interpolation (p-value calculating) by reversing probabilities and quantiles (2 and 3 argument).
