We got a lm object from and want to extract the standard error lm. R: standard error output from lm. what @csgillespie refers to is the residual standard.
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.
