Reappraising medfly longevity: A quantile regression survival analysis

In this article we explore the usefulness of a quantile regression formulat ion of reanalyzing a large experimental study that monitored age-specific m ortality in a sample of roughly 1.2 million Mediterranean fruit flies. The quantile regression approach appears useful in refining several of the conc lusions drawn from the original study including the apparent decline in mor tality rates at advanced ages, and the gender crossover effect in survival functions for medflies.
