stdiagn

0th

Percentile

Produces some summary plots for clustering analysis

Keywords

Usage
stdiagn(pts, stkh, stse, stmc=0,Dzero=FALSE)
Arguments
pts
A set of points, as used in Splancs
stkh
An object returned from stkhat
stse
An object returned from stsecal
stmc
An object returned from stmctest
Dzero
FALSE - default D plot, TRUE Dzero plot
Details

Four plots are produced on the current graphics device. The first plot is simply a map of the data. The second is a perspective plot of the difference between space-time K-function and the product of spatial and temporal K-functions. The third plot is of the standardised residuals against the product of spatial and temporal K-functions. If the Monte-Carlo data is given the fourth plot is a a histogram of the test statistics, with the value for the data indicated with a vertical line. See Diggle, Chetwynd, Haggkvist, and Morris (1995) for details.
