R-squared between the allele dosage of imputed genotypes and the allele dosage of truth genotypes is a commonly used metric for evaluating the performance of imputation methods. It has been shown that improvements in R-squared can translates to increases in statistical power of GWAS.

Note also that the R-squared statistic is calculated on groups of variants within a MAF bin ("aggregate R2").
