determines that the individual specified as the first factor is not the causative individual and further determines that the second factor does not include the causative individual in a case where the error occurrence status is not biased and is favorable, and
determines a probability of the individual specified as the first factor being the causative individual and sets a determination result as the first determination result in a case where the error occurrence status is not biased and is not favorable,

the second determination section
determines that the individual specified as the second factor is not the causative individual and determines a probability of a specific individual of which the error occurrence status is inferior among the individuals of the determination target as the first factor being the causative individual in a case where the error occurrence status is biased,
determines that the individual specified as the second factor is not the causative individual and further determines that the first factor does not include the causative individual in a case where the error occurrence status is not biased and is favorable, and
determines a probability of the individual specified as the second factor being the causative individual and sets a determination result as the second determination result in a case where the error occurrence status is not biased and is not favorable, and

the cause estimation section
identifies the causative individual satisfying the first determination result and the second determination result in a case where the first determination result and the second determination result do not conflict with each other, and
