Extrapolative models
/ɪkˈstræp.ə.lə.tɪv ˈmɒd.əlz/
Models that project future outcomes by extending past trends beyond the range of observed data. In longevity analysis, extrapolative models are often used to forecast mortality rates or life expectancy by assuming that historical patterns (such as improvements in survival) will continue into the future. These models can be sensitive to the choice of trend and may not account for emerging risks or step-changes in behaviour or health, for example.
