IBEE Computer Code
The following two files describe and contain the
S-plus code used to compute the IBEE
and Independence estimates for the Meron vegetation data in "Analyzing Spatially
Distributed Binary Data Using Independent-Block Estimating Equations" by Oman,
Landsman, Carmel and Kadmon.
The code may be used for binary responses from an equally-spaced rectangular grid,
and uses an exponential covariance function for the latent normal field (it may be
easily adapted to handle other types of covariance functions).
The S-plus statements are in a number of programs ( ibee.1 - ibee.6) which are to be
run sequentially. Before running them, the user must prepare data matrices and define
a number of parameters, as described in the comments of ibee.1. The programs use a
number of functions, whose code is also available.
ibee.readme.rtf Contains a brief description of the programs, the names of the functions,
and the calling sequence for the functions.
the code for ibee.1 - ibee.6 and the functions, as one long
The first line of each program or function is in boldface, and the last line
is followed by a blank line, in order to simplify copying and pasting into
the Splus window. The programs and functions have numerous
