In Section 1.1.1, we presented a potential methodology for the development of Altman's model [1]. We commenced at a high-resolution level, beginning with the final mathematical expression, and subsequently proceeded to a lower-resolution level until we reached an expression that could be elucidated in everyday language. In practice, however, the modeling process progresses from a low-resolution level of analysis, which is conveyed in simple terms, to a high-resolution level of analysis, which is expressed in mathematical expressions. But prior to any analysis, it is important to have a deep understanding of the system or phenomenon at study.
