1. A processor-readable medium comprising code representing instructions to cause a processor to: generate at least one parameter estimate of a probability regression model for cardiovascular disease at least partially based on (1) a plurality of predictors generated from cardiovascular sound signals of a plurality of subjects and (2) disease status information for cardiovascular disease of the plurality of subjects; and determine a probability of cardiovascular disease for a new subject with the probability regression model, the probability of cardiovascular disease being generated at least partially based on the at least one parameter estimate and another plurality of predictors generated from cardiovascular sound signals of the new subject.
