  We establish large deviation estimates related to the Darling--Kac theorem
and generalized arcsine laws for occupation and waiting times of ergodic
transformations preserving an infinite measure, such as non-uniformly expanding
interval maps with indifferent fixed points. For the proof, we imitate the
study of generalized arcsine laws for occupation times of one-dimensional
diffusion processes and adopt a method of double Laplace transform.
