what is a Bayesian model with an unknown average Bayesian model with unknown mean and variance, lognormal prior what is the lognormal prior of a Bayesian model what is the probability of using the posterior posterior r value of the model for the Bayesian model how to estimate posterior value in a bayesian model what models include the posterior mean average posterior posterior value of bayesian model what model would assume a lognormal prior where should i estimate posterior what model has an unknown variance and lognormal mean? what model does the prior parameters of lognormal prior include what is the prior parameter in a bayesian model which type of parameter is unknown in a bayesian model what is the posterior of the model when the mean is unknown what is the prior posterior of a bayesian model what is the value of $i in a bayesian model if a model has a mean and variance that is different from its prior model and is a lognormal model, then what kind of prior model does it have? what is the model for a bayesian model when the posterior t is unknown in a bayesian model why do we assume we have a lognormal
