SBUX, for example, pattern computer error is really big, way large than muhat. Magnitudes of standard error tell that they are poor estimates for dead on tar stay value.

009462 resembling explanation as that for sigma2. Standard errors are small relative to sigmahat.vals. Look at SBUX, SE is 0.009 when sigmahat is 0.103.
