Test transition matrix construction for different variance values

Source: R/tester_matrices.R
test_matrices.Rd

This function tests whether transition matrices can be constructed for different variance values, given fixed deviation (D) and sensitive threshold (js) parameters. It uses binary search to find the minimum variance value that allows matrix construction.

Usage

test_matrices(D, js = 0, Vmin = 0, Vmax = 30, precision = 1)

Arguments

D

integer. Deviation parameter (must be strictly positive)

js

integer. Threshold for sensitive values (default: 0). If js=0, only value 0 will be forbidden

Vmin

numeric. Minimum variance value to test (default: 0)

Vmax

numeric. Maximum variance value to test (default: 30)

precision

numeric. Precision for the binary search algorithm (default: 1)

Value

NULL if no solution exists in the requested interval, or numeric value of the variance that makes the matrix constructible

Examples

# Test with basic parameters
test_matrices(5, 1)
#> Tested interval: [ 0 ; 30 ]
#> Tested interval: [ 0 ; 15 ]
#> Tested interval: [ 0 ; 7.5 ]
#> Tested interval: [ 0 ; 3.75 ]
#> Tested interval: [ 0 ; 1.875 ]
#> Tested interval: [ 0.9375 ; 1.875 ]
#> [1] 1.875
