Compare to default tree, here total levels of the tree were reduced to 5 levels but not able to
predict properly up to last level.

Compare to default tree, here total levels of the tree were reduced to 4 levels but not able to
predict properly. Here because of the large minimum support some important data for the
decision were missing.
3) Conclusion: By comparing all above trees of different parameters, below parameters
were best as the MINIMUM_SUPPORT was not too small and too large, so it not
exclude high priority data and not include low priority data.
