Abstract: | Background The imputation of missing values is necessary for the efficient use of DNA microarray data, because many clustering algorithms
and some statistical analysis require a complete data set. A few imputation methods for DNA microarray data have been introduced,
but the efficiency of the methods was low and the validity of imputed values in these methods had not been fully checked. |
