  Efficiently sampling from the P\'olya-Gamma distribution, ${PG}(b,z)$, is an
essential element of P\'olya-Gamma data augmentation. Polson et. al (2013) show
how to efficiently sample from the ${PG}(1,z)$ distribution. We build two new
samplers that offer improved performance when sampling from the ${PG}(b,z)$
distribution and $b$ is not unity.
