Abstract (in Japanese) (See Japanese page) 
(in English) For probabilistic models involving irreversible saturation effects, we provide extended definitions of the score function, Fisher information, and Cram'{e}r--Rao lower bound, which cannot be dealt with in the literature so far. Saturation effects are almost inevitable in observation of signals, and various attempts have been proposed to estimate original signals or their underlying parameters from saturated signals. In general contexts of parameter estimation, comparison with the Cram'{e}r--Rao lower bound is widely used to evaluate performance of an estimator; however, in observation with irreversible saturation effects, it cannot be derived because the score function and Fisher information cannot be defined owing to the nonexistence of the probability density function of the model. In this work, we extend their definitions on the basis of measure theoretic approach without using the probability density function and demonstrate the effectiveness of our theory for a simple model involving irreversible saturation effects as an example.
