Returns the best estimate of the lower bound of the confidence interval given <i>kappa</i>,
the number of standard deviations from the mean.
@param kappa the given number of standard deviations from the mean: 1, 2 or 3.
@return the best estimate of the lower bound of the confidence interval given <i>kappa</i>.
