st: -variog- available from SSX
Thanks to Kit Baum, a package -variog- is
available from SSC. It contains two
programs. -variog- calculates and
graphs a semi-variogram for regularly
spaced data in one dimension. -variog2-
calculates and graphs a semi-variogram for
point-based data in two dimensions, whether
regularly or irregularly spaced.
Please note that these are minimal programs only
arising from a small burst of teaching some (very
elementary) spatial statistics. Neither variogram
model fitting nor kriging is supported, nor is
either on my list of things to do. That said,
someone might find them interesting or useful.
Stata 8 is required.
