One needs to evaluate the risk by studying the standard deviation of the expected value of each asset given its risk. For (N) assets, there exists a vector (mu.

Extract the estimated standard deviation of the errors, the “residual standard deviation” (misnomed also “residual standard error”, e.g., in summary.lm() 's output, from a fitted model). Many classical statistical models have a scale parameter, typically the standard deviation of a zero-mean normal (or Gaussian) random.
