Summary Statistics
Description
Computes the summary count statistics of a field given an interaction structure and a restriction family.
-
cohist()
computes the co-ocurrence histogram. -
smr_stat()
computes the co-ocurrence histogram, then converts it into a vector of sufficient statistics given afamily
of restrictions.
Usage
smr_stat(Z, mrfi, family)
cohist(Z, mrfi)
vec_description(mrfi, family, C)
Arguments
Z |
A |
mrfi |
A |
family |
The family of parameter restrictions to potentials. Families
are:
|
C |
The maximum value of the field. |
Details
The order the summarized counts appear in the summary vector matches
the order in smr_array()
.
Value
A numeric vector with the summarized counts.
An array representing the co-ocurrence histogram of Z
in the relative
positions contained in mrfi
. Each row and column corresponds a pair of values
in (0, ..., C)
and each slice corresponds to
A data.frame
describing the relative position
and interaction associated with each potential in the vector
form in each row, in the same order.
