A simple model of life expectancy with subjective parameters

The use of deterministic or stochastic models to describe an observable phenomenon is considered to present enormous difficulty when evaluating the subjective parameters. In those cases where randomness cannot be established, or when there are not sufficient data available, it is believed that fuzzy theory is the appropriate approach to the problem. Utilizes the classical stochastic Boltzman model to compare the stochastic and fuzzy techniques. Gives a comparison of a specific case study: the life expectancy of individuals whose causa mortis is affected by poverty.
