Abstract: The purpose of the present study is to study the differentials, patterns and trends of expectation of life (ex) of Bangladesh during 1961-1991. For this, the expectation of life (ex) of Bangladesh in the census years 1961, 1974, 1981 and 1991 have been used in this study. A few mathematical models have been fitted to ex and f(x)=x+ex only for male of Bangladesh in 1961 and it is found that they follow polynomial models. The Cross-Validity Prediction Power (CVPP) and F-test are also applied to these models to check the validity and significance of the models.
