data mining algorithm extracts interesting patterns (such as logic rules and clusters) that could other-wise be extremely difficult for us to extract [15, 7]. Data preprocessing and cleansing play a vital role in data mining by ensuring good quality of data. Data-cleansing tasks include imputation of miss-

Imputation of Missing Data Using R Package 133 (3) cold deck imputation – missing values are filled in by a constant value from an external source; (4) predictive mean matching – combination of regression imputation and hot deck method – the method starts with regressing the variable to be imputed – Data elimination cum interpolation for imputation Figure 2 shows the flowchart of data elimination cum interpolation for imputation preprocessing approach as proposed in this study. As discussed in section 2.1, data elimination filtered instances containing missing value of more than 30%.

Scenario 1 (generation of missing data on one single variable (age)) At this EPV, five variables were retained in the gold model. At 10% missing rate, the results of variable selection in all models were the same as gold model. However, median substitution was the only method which estimated coefficient of age in a biased way.
