Calculation of probabilities for binary sequences

Description

Calculation of proabilities for binary sequences based on the final matrix generated by the genetic algorithm

Usage

sequence_probs(Xt)

Arguments

Xt	Representative matrix generated by the genetic algorithm with iter_matrix

Details

Observation of binary correlated binary data can be expressed as binary sequences. In the case of two binary variables possible observations are (0,0), (0,1), (1,0) and (1,1). In general, 2^m binary sequences are possible, where m is the number of binary variables. Based on the representative matrix generated by the genetic algorithm the probability for each binary sequence is determined.

Value

A vector of probabilities for the binary sequences

### Generation of the representive matrix Xt
X0 <- start_matrix(p = c(0.5, 0.6), k = 1000)
Xt <- iter_matrix(X0, R = diag(2), T = 10000, e.min = 0.00001)$Xt
