We have derived an empirical relation between stellar mass and planet occurrence by measuring the occurrence rate of planets from Doppler surveys spanning a wide range of stellar masses. We used Bayesian parameter estimation to fit a parametric model to the sample of detections and non-detections in our data set, while simultaneously correcting for the effects of metallicity. Remarkably, we find no correlation between stellar metallicity and planet occurrence for stars with masses greater than 1.5 Msun. We see a slow increase in the measured planet occurrence for stars with masses less than 1.5 Msun which rises steeply thereafter. There is a much higher chance of finding a gas giant planet around an A-type star, regardless of its metallicity, than around either an M-dwarf or Sun-like star.
