Generate random indices
Description
The ahp.ri
function calculates the mean consistency indices of a specific numbers of random number pairwise comparison matrices.
The random index of one pairwise comparison matrix is given as below, where lambda
is the maximum eigenvalue and n
is the number of attributes.
RI = (\lambda-n)/((n-1)
ahp.ri
creates nsims
number of pairwise comparison matrices with number of dimensions=dim
, and returns its average.
Usage
ahp.ri(nsims, dim, seed = 42)
Arguments
nsims |
Number of random pairwise comparison matrices to be generated. Processing time increases substantially with higher |
dim |
Number of dimensions of the matrix. |
seed |
The random number generator seed for reproducibility, which is same as |
Value
The generated random index, which is numeric.
