Abstract: A challenge in carrying out matching analyses is to deal with undefined log ratios. If any reinforcer or response rate equals zero, the logarithm of the ratio is undefined: data are unsuitable for analyses. There have been some tentative solutions, but they had not been thoroughly investigated. The purpose of this paper is to assess the adequacy of five treatments: omit undefined ratios (OMIT), full information maximum likelihood (FIML), mean divided by 100 (M/100), constant 1/10 (1/10) and constant .50 (CONS). Based on simulations, the treatments are compared on their estimations of variance accounted for, sensitivity and bias. The results show that FIML and OMIT had the best overall performance with negligibly biased and more accurate estimates than M/100, 1/10 and CONS. The study suggests that M/100, 1/10 and CONS should be avoided and recommends FIML to deal with undefined log ratios in matching analyses.
