The Cryogenic Underground Observatory for Rare Events (CUORE) experiment set the most stringent limit on the neutrinoless double-beta (0νββ) decay half-life of 130Te with 2 ton yr TeO2 analyzed exposure. In addition to 0νββ decay, the CUORE detector -- a ton-scale array of nearly 1000 cryogenic calorimeters operating at ∼10 mK -- is capable of searching for other rare decays and interactions over a broad energy range. For our searches, we leverage the available information of each calorimeter by performing its optimization, data acquisition, and analysis independently. We describe the analysis tools and methods developed for CUORE and their application to build high-quality datasets for numerous physics searches. In particular, we describe in detail our evaluation of the energy-dependent detector response and signal efficiency used in the most recent search for 0νββ decay.
