41. Generally the prior probability is estimated using the prevalence of a disease within a population or at a given testing location. 42. P ( S | \ theta ) is the prior probability of the ancestral states for a given model and tree. 43. If, in addition, the columns of X are a sample from the prior probability distribution, then the columns of 44. :You need to know the prior probability that the coin is biased before you can answer such a question precisely. 45. Note that I do not'set the prior probability as 50 / 50 in favour of getting a six '. 46. For sufficiently nice prior probabilities , the Freedman and Persi Diaconis continued to work on the case of infinite countable probability spaces. 47. The determinant of Fisher's information matrix is of interest ( for example for the calculation of Jeffreys prior probability ). 48. The tables below specify the various prior probabilities , i . e . the probabilities in the absence of any further information. 49. But it doesn't make ANY sense for me, because if you take prior probability into account tests are meaningless. 50. To meet the needs of science and of human limitations, Bayesian statisticians have developed " objective " methods for specifying prior probabilities .
