B coefficients estimates.
Defines the logistic regression B coefficients. Suppose y takes values in k ordered categories, and let p_ij be the cumulative probability that y(i) falls in the j'th category or higher. Ordinal logistic regression model is defined as:
logit(p_ij) = theta(j) + A_i'B , i = 1,..,length(Y), j = 1,..,k-1,
where A_i is the i'th row of A . The number of ordinal categories k is taken to be the number of distinct values of int(y). If k is 2 the model is ordinary logistic regression.
Set B values to define initial estimates for B coefficients. Setting B values is not mandatory. You can also set TMtxLogistReg::AutoInitEstimates to true and force the algorithm to calculate initial estimates for TMtxLogistReg::B and TMtxLogistReg::Theta. After the TMtxLogistReg::Recalc call B stores logistic regression model B coefficient estimates.
