%description
Fit the log binomial regression model (LBM) by Exact method. Limited
parameter space of LBM causes trouble to find admissible estimates and
fail to converge when MLE is close to or on the boundary of space. Exact
method utilizes the property of boundary vectors to re-parametrize the
model without losing any information, and fits the model on the standard
fitting algorithm with no convergence issues.
