KS2D_NRR Documentation

Data from Figure 14.7.1 of Numerical Recipes

Description

Data ‘digitized’ from Figure 14.7.1 of Numerical Recipes

Format

A data frame with 95 observations on the following 4 variables:

obs

Observation number.

x

X coordinate.

y

Y coordinate.

group

Which coordinate set (‘triangles’ or ‘squares’).

Note

The data in Figure 14.7.1 apparently had 65 triangles and 35 squares. These data have only 63 triangles and 32 squares.
