The AHP method (Analytic Hierarchy Process) is a multi-criteria decision-making method addressing
choice and outranking problems. The method enables to perform the analysis of alternatives in each
type of criterion and then provides a global performance of each alternative in the decision context.
The main difference of this package is the possibility of evaluating the alternatives using quantitative
data, by numerical representation, and qualitative data, using the Saaty scale, providing preference
relation between variables by a pairwise evaluation.

Estimation and Testing of Average Hazard Ratios
Methods for estimation of multivariate average hazard ratios as defined by Kalbfleisch and Prentice. The underlying survival functions of the event of interest in each group can be estimated using either the (weighted) Kaplan-Meier estimator or the Aalen-Johansen estimator for the transition probabilities in Markov multi-state models. Right-censored and left-truncated data is supported. Moreover, the difference in restricted mean survival can be estimated.
