1. An assessment support program for an automatic braking system executed by a computer having at least a CPU, the assessment support program executing the following steps: a regression analysis step making the CPU obtain a probability distribution by a logistic regression analysis with reading out from a memory a result of a test of whether or not a vehicle equipped with the automatic braking system collides with an obstacle under actuation of the automatic braking system; and an assessment step making the CPU function as a part that constitutes an assessment unit that makes an assessment of performance of the automatic braking system on the basis of the probability distribution; wherein: an explanatory variable in the logistic regression analysis is a relative speed of the vehicle relative to the obstacle before the actuation of the automatic braking system; and a response variable in the logistic regression analysis is an occurrence probability of an event in the result of the test.
