generate_random_integer_Gamma: Generate a random Gamma matrix containing only integers

In graphicalExtremes: Statistical Methodology for Graphical Extreme Value Models

Generate a random Gamma matrix containing only integers

Description

Generates a random variogram Matrix by producing a \d1xd1 matrix B with random integer entries between -b and b, computing S = B %*% t(B), and passing this S to Sigma2Gamma(). This process is repeated with an increasing b until a valid Gamma matrix is produced.

Usage

generate_random_integer_Gamma(d, b = 2, b_step = 1)

Arguments

d	Number of rows/columns in the output matrix
b	Initial b used in the algorithm described above
b_step	By how much b is increased in each iteration

Value

A numeric \dxd variogram matrix with integer entries
