Produces some summary plots for clustering analysis
Usage
stdiagn(pts, stkh, stse, stmc=0)
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
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 (1993) for details.
