Percentage of single, first, middle and last authorship papers vs. the size of portfolio. Important note: the larger the portfolio, the less data we have (No. portfolios), thus the rows had been bootstrapped 10,000 times. This is crucial for more than ~50 item portfolios where we have less than 1,000 of portfolios passing the threshold. The data refers to all articles (both research and non-research).
