Intuition Behind the Bayesian LASSO [Alex Chinco]Imagine youve just seen Apples most recent return, r, which is Apples long-run expected return, \mu^\star, plus some random noise, \epsilon \overset{\scriptscriptstyle \mathrm{iid}}{\sim} \mathrm{N}(0, \, 1): (1) \begin{align*} r &= \mu^\star + \epsilon. \end{align*} You want to use this realized return, r, to estimate Apples long-run expected return, \mu^\star. The LASSO is a
