Summary/Abstract: In contrast with most multivariate statistical analysis methods, classification tree is an example of the learning algorithm coping with missing values in special, original way. In the paper the influence of some selected missing data techniques on the results of object classification using CART and CRUISE classification trees was assessed. All the procedures were compared by artificially simulating different proportions and mechanisms of missing data using complete data sets mainly from the UCI repository of machine learning databases.
