Description:
DTREG is a powerful statistical analysis program that generates
classification and regression decision trees that model data and
can be used to predict values. DTREG is a robust application that
is installed easily on any Windows system. DTREG reads Comma
Separated Value (CSV) data files that are easily created from
almost any data source. Once you create your data file, just feed
it into DTREG, and let DTREG do all of the work of creating a
decision tree and pruning it to the optimal size. Even complex
analyses can be set up in minutes. DTREG can build Classification
Trees where the target variable being predicted is categorical and
Regression Trees where the target variable is continuous like
income or sales volume. By simply checking a button, you can direct
DTREG to build a classic single-tree model, a TreeBoost model
consisting of a series of trees or a Decision Tree Forest model.
DTREG uses V-fold cross-validation to determine the optimal tree
size. This procedure avoids the problem of "overfitting" where the
generated tree fits the training data well but does not provide
accurate predictions of new data. DTREG uses a sophisticated
technique involving "surrogate splitters" to handle cases with
missing values. This allows cases with some available values and
some missing values to be utilized to the maximum extent when
building the model. It also enables DTREG to predict the values of
cases that have missing values. DTREG can display the generated
decision tree on the screen, write it to a .jpg or .png disk file
or print it. When printed, DTREG uses a sophisticated technique for
pagenating trees that cross multiple pages.
