COMMAND(1)

NAME
tquest - classify an example using a decision tree

SYNOPSIS
tquest [-pvul] attribute_file tree_file

tquest [-pvul] stem

DESCRIPTION

tquest is an interactive program to classify an example. The example is classified according to the given tree. The user will be prompted to enter attribute values as they are required. The second form uses the stem instead of explicitly specifying the files, and assumes files "stem.attr" and "stem.tree" exist. If the attribute_file contains a utilities specification, then average utility is also printed with any statistics and the best decision is calculated to maximize expected utility. Otherwise, the class with maximum probability is chosen (i.e., minimum errors utility).

OPTIONS

-l  Loop indefinitely, so keep querying for more examples.

-p  For each example, print out the probability estimates for each class. When coupled with the -v option prints their variance as well.

-u  Print the expected utility or error for this example.

-v  A standard deviation of the probability estimates is calculated and printed as well.
