+Impute allele frequencies set to missing according to another minimum depth parameter, i.e. `--min-depth-set-to-missing`. Two imputation algorithms are currently available (a third one is in the works):
 
 1. computationally efficient mean value imputation, and
 2. adaptive linkage disequilibrium-based k-nearest neighbour imputation (an extension of [LD-kNNi](https://doi.org/10.1534/g3.115.021667)).
