Neymanâ€”Pearson theory can accommodate Dating website for 14-15 year olds prior probabilities and the costs of actions resulting from decisions. One of them is observable ,endogenous variables which acts as indicators and the other one is non-observable exogenous variables which cannot be observed and hypothetical.
