In the line after formula (20) on page 227, \( {C}_{\widehat{\mathbf{y}}},{C}_{\widehat{\mathbf{z}}},{C}_{\overline{\mathbf{g}}} \) should read \( {C}_{\widehat{\mathbf{y}}\prime },{C}_{\widehat{\mathbf{z}}},{C}_{\overline{\mathbf{g}}\prime } \)

In Formula (21) on page 227, \( {C}_{\widehat{\mathbf{y}}}={\widehat{\upsigma}}^2{\left(\overline{\sum}{\prime}^{\dagger}\right)}^2 \); should read \( {C}_{\widehat{\mathbf{y}}\prime }={\widehat{\upsigma}}^2{\left(\overline{\sum}{\prime}^{\dagger}\right)}^2 \);

On page 230, in the 7th line of the conclusion, it should read “estimated parameters of the decomposed model (9);”
