👉 In statistics and probability theory, "posterioristically" refers to a way of estimating parameters or probabilities based on past observations. It involves using prior knowledge about the parameters to inform the current estimates. In other words, it means that when you're trying to estimate something (like a parameter), you first try to understand what information is available and how likely each possible value of the parameter is. Then, you use this understanding to make an educated guess or prediction based on past observations. This way,
