tipplt

Tippett plot

R

tipplt(same, diff, ...)

Python

crimlab.tipplt(same, diff)

Command line

crimlab tipplt --same VALUE --diff VALUE

For each value on the axis, the share of same-source and of different-source likelihood ratios above it. A good system keeps the same-source curve high to the right of 0 and the different-source curve low; where each crosses 0 shows the rate of misleading evidence. proof() records no theorem for this plot.

Parameters

same

Likelihood ratios from same-source comparisons: positive numbers.

diff

Likelihood ratios from different-source comparisons: positive numbers.

...

Passed to graphics::plot().

Returns

Invisibly, a list of two data frames, same and diff, each with log10lr and share (the share of ratios at or above it).

Examples

tipplt(same = c(50, 200, 8, 0.5), diff = c(0.01, 0.2, 1.5, 0.001))
