1. A distribution goodness-of-fit test device for testing whether measured data matches an estimated probability distribution, comprising:
- a counting section determination unit that determines according to the number of the measured data, widths of counting sections for counting the measured data;
a counting unit that counts the numbers of data in the respective determined counting sections and records the count of the numbers of data; and
a goodness-of-fit test unit that performs a goodness-of-fit test based on the recorded numbers of data in the respective counting sections.

Abstract
A distribution goodness-of-fit test device for testing whether measured data matches an estimated probability distribution has a counting section determination unit, a counting unit and a goodness-of-fit test unit. The counting section determination unit determines according to the number of the measured data, widths of counting sections for counting the measured data. The counting unit counts the numbers of data in the respective determined counting sections. Also, the goodness-of-fit test unit performs a goodness-of-fit test based on the numbers of data in the respective counting sections.
