  1. Note. To make sure zero sample mean and unit sample standard deviation, the stock returns, good extreme returns and bad extreme returns are first filtered, and then standardized using the following formula
  2. Zt = [Xt ‐ M(Xt)]/S(Xt)
  3. where M(Xt) is the sample mean of Xt, S(Xt) is the sample standard deviation of Xt
