Decision Tree Creation - Java Application Enhancement

The programmer must have experience with iNode and need to know how to create multiple decision trees using java. Project objective: Enhance existing java application that has missing value replacement algorithm implemented using the cumulative average mean value calculated for each variable. All original values are used to calculate the mean for each variable and stored in an array. When missing value are encountered, the value stored in the array for the variable (with missing value) will be used to replace it. All replaced values will be excluded from the calculation of the mean for the respective variables.
