Trong sách " Bayesian methods in finance" có đoạn :
Suppose we are interested in analyzing the returns on a given stock and
have available a historical record of returns. Any analysis of these returns,
beyond a very basic one, would require that we make an educated guess
about (propose) a process that might have generated these return data.
Assume that we have decided on some statistical distribution and denote
it by p(y|θ),where y is a realization of the random variable Y (stock return) and θ is a parameter specific to the distribution, p.

Nhưng mình là dân thống kê nên không hiểu cụm từ "STOCK RETURNS" dịch ra là gì cả, mong các bạn giup vơi, cảm ơn nhiều
