A case example of differences between the standard AR measure used in most event studies and the adjusted AR is provided. In tests of 240 equity private placements of publicly held companies between 1983 and 1996, the adjusted AR measure dominates the standard AR measure across various sample sizes. As the sample size decreases, the adjusted measure retains the ability to detect material and significant price increases while the standard AR measure's ability declines.TOPICS: Private equity, statistical methods, portfolio construction, performance measurement %U https://jpe.pm-research.com/content/iijpriveq/9/3/73.full.pdf
