AUTOCORR
-
- Computes Moran+s -I+ first lag autocorrelation statistic for
an image, along with confidence tests. Non-rectangular regions
can be analyzed by defining a binary mask.
CENTER
-
- Computes mean center (weighted or not) of a point distribution
and standard radius (the two-dimensional equivalent of a standard
deviation).
CRATIO
-
- Computes the compactness ratio of polygons given corresponding
area and perimeter images.
QUADRAT
-
- Computes the density, variance and variance-mean ratio of
quadrat cell counts.
TREND
-
- Calculates the best fit linear, quadratic or cubic trend surface
to a set of irregular cell control points by least-squares procedures.
Produces new images of the trend surfaces in addition to surface
statistics.
CROSSTAB
-
- Performs image crosstabulation and crosscorrelation.
RANDOM
-
- Creates random images according to either a rectilinear or
normal distribution. In the case of a normal distribution, the
mean and standard deviation to be used may be specified.
PROFILE
-
- Creates profiles over space or over time.
REGRESS
-
- Performs regression analysis on images or attribute values
files.
SAMPLE
-
- Creates systematic, random and stratified random point sampling
schemes.
PATTERN
-
- Evaluates pattern measures of relative richness, diversity,
dominance index, fragmentation index, NDC, CVN and BCM.
