do i multiply variance and prior to get posterior what is the difference between the variance of the posterior and likelihood if i multiply probability and prior does the variance of the result pdf become narrower than that of likelihood and prior can variance of two pdfs always be narrower what is variance of variance in pdf is variance of the posterior narrower than likelihood how to determine if pdf is the same as likelihood when you multiply vs posterior how many pdf are in a multiplication if you multiply two pdfs what does the variance become a little narrower? does the variance of the posterior of a multiple pdf become narrower when multiplying likelihood and prior? does variance decrease when multiplying multiple pdfs what does the difference between probability and prior mean in calculating probability and prior? what is the variance on a pdf multiplied by two when you multiply two pdf files what happens to the variance why does the variance of the posterior always equal what is the variance when multiplying the PDFs when do i multiply probability and prior to get the posterior if multiplied by probability and prior do the variances of the results narrow does variance of two pdfs always increase when multiplying probability
