Exact two-sided p-values in natural exponential families: coincidence, non-uniqueness, and sample-size stability

Shaul K. Bar-Lev, Linard Hoessly

We study the non-uniqueness of exact two-sided $p$ -values in continuous one-parameter natural exponential families (NEFs). For directed one-sided problems, the tail $p$ -value agree…

The limiting behavior of some infinitely divisible exponential dispersion models

Shaul Bar-Lev, Gerard Letac

Consider an exponential dispersion model (EDM) generated by a probability $μ$ on $[0, \infty)$ which is infinitely divisible with an unbounded Lévy measure $ν$ . The Jorgensen set…

Increasing hazard rate of mixtures for natural exponential families

Shaul K. Bar-Lev, Gerard Letac

Hazard rates play an important role in various areas, e.g., reliability theory, survival analysis, biostatistics, queueing theory and actuarial studies. Mixtures of distributions a…
