KNN imputed ratio. Table shows the maximal values can be imputed by KNN algorithm and the number of values is exactly imputed in each microarry data. The imputed ratio is the proportion of the real imputed genes to the maximal genes. The less the imputed ratio is, the more imputed data similar to real experiment data. The result shows that the imputed ratios of the microarray data are all less than 50%, it seems to be reasonable to assume the imputed dataset is good enough to analyze the gene regulatory network.
