Rising tail in Bradford distribution: Its interpretation and application

The right tail of the Bradford distribution has been considered to be straight or drooping. This paper reports cases in which the right tail is rising upward, explains and verifies conditions of its occurrences, interpretes it and proposes its application to evaluation and forecasting of technological development at the basic research stage.
