The original version of this article has an error in the Eq. (9).The corrected text and Eq. (9) is given below.

The time series of the IE in “actual” metric (${}^{est}\widehat{IE}_{t}^{m\_1}$) is calculated by combining the results in steps 2 and 3.1 as follows:

${}_{ }^{est} \widehat{IE}_{t}^{m\_1} = \overbrace {{{}_{ }^{ols\_est} \hat{\gamma }_{0}^{*} }}^{{step{ }2}} + \left\{ {\begin{array}{*{20}l} {\sum\nolimits_{i = 1}^{5} {\underbrace {{{}_{ }^{est} \hat{\gamma }_{i}^{*} }}_{{step{ }3.1}}} x_{i,t}^{ } } \hfill & {if \;est = cb} \hfill \\ {\begin{array}{*{20}c} \\ {\sum\nolimits_{i = 1}^{5} {\underbrace {{{}_{ }^{est} \hat{\gamma }_{i}^{*} }}_{{step{ }3.1}}\left( {\sigma_{{y_{1} }} /\sigma_{{x_{i} }} } \right)x_{i,t}^{ } } } \\ \end{array} } \hfill & {if \; est = pls} \hfill \\ \end{array} } \right.$, with $i = 1, \ldots ,5;\;t = 1, \ldots ,T$ (9).
