On the Geometric Mean Method for Incomplete Pairwise Comparisons
One of the most popular methods of calculating priorities based on the pairwise comparisons matrices (PCM) is the geometric mean method (GMM). It is equivalent to the logarithmic least squares method (LLSM), so some use both names interchangeably, treating it as the same approach. The main difference, however, is in the way the calculations are done. It turns out, however, that a similar relationship holds for incomplete matrices. Based on Harker's method for the incomplete PCM, and using thedoi:10.3390/math8111873 fatcat:pnh4bzvru5cozhnfvgnxin56kq
