Correct credit distribution: A model for sharing credit among coauthors

On the basis of some assumptions (e.g. Minimum and Maximum Contribution Scores of authors) a simple equation is introduced for calculating individual contribution scores of co-authors of multi-authored papers. The calculated Corrected Contribution Scores are in good agreement with the data obtained empirically, earlier. It is suggested that individual percentage contributions should be declared by the co-authors in the by-line of papers.
