1. The problem statement, all variables and given/known data Hi all. Lets say i have some data points (x, y) (we will call these data 'D'). There is no uncertainty in x, and the uncertainty in y is 1. I believe t hat x and y are connected as y = ax2, and I want to find the probability of a having a certain value given the data D. 3. The attempt at a solution I know how to find the probability of y having some specific value given some data points for y with an uncertainty. But in this case, x and y are connected by a. I thought that perhaps the relative unvertainty in y is the same for a? Thanks in advance. Sincerely, Niles.
