In the published article, it was claimed, erroneously, that: ‘The margins of total population were reduced to 63, 65 and 56% after correction on X, Y and Z axes, respectively.’
This line should read: ‘The margins of total population were reduced by 63, 65 and 56% after correction on X, Y and Z axes, respectively.’
This error was made by the publisher during the production process, for which we apologise.
