“…The widely applied Chiang method of life expectancy estimation is just based on such kind of abridged dataset, that is much more popular than cohort dataset. In [12] we proposed a novel method of life expectancy estimation for the abridged dataset with numbers of deaths and of population are aggregated along age groups. The novel method based on the Weibull distribution with parameters localized in all age groups gives a good estimation of life expectancy.…”

“…Especially, the authors of [1], as well as [22], [14], and [31] pointed out that survivorship data can be well fit to the Weibull distribution. For that, in [12] we use the Weibull distribution to model the human survival process and to develop a new tool of life expectancy estimation.…”

“…In that situation, the numerator in the equation of any age-specific mortality rate might contain "misplaced" deaths and does not include those who had been mis-allocated to neighboring age groups. To avoid the aforementioned inconsistence, in [12] we proposed to use abridged data for life expectancy estimation, that are organized differently from MAD. Specifically, the last day (December 31) of the current observation year is used to record individual age.…”

“…In [12] we describe in more detail the derivation to get the number pairs (n j ; d j ) from the number pairs (pop j ; death j ) and to estimate the local parameters λ 1 , λ 2 , ..., λ 19 . At first, since there is only a half-year shift between July 1 and December 31 of the currently observed year, we can assume that n j = pop j for all j = 1, 2, ..., 19.…”

“…Avoiding the use of abridged life tables that may cause unexpected problems in LE estimation, the recent work [12] proposed a novel method of life expectancy estimation based on the theoretical background of survival process with local parametric Weibull distributions. The new method, called "Local parametric method" (LPM), can be applied to abridged datasets instead of the Chiang method, showing certain advantages over the old one.…”

Concerning the local parametric estimation method, a novel method of life expectancy estimation, the article derives a formula to calculate the variance of that estimation. Specifically, we provide the theoretical base of the variance formula, then prove the approximation to normal distribution of the life expectancy local parametric estimation. Extensive experiments with real-world datasets show that the local parametric method provides less biased estimation with lower variance in comparison to the Chiang method. This confirms the advantages of the new life expectancy estimation method over the Chiang estimation method. The lower variance of estimation allows the statistical tests to get the higher performance in detection of life expectancy estimation differences. The new life expectancy estimation method can be useful in the assessment of the health inequality in small area settings by conducting statistical tests.

In Chile and worldwide, life expectancy has consistently increased over the past six decades. Thus, the purpose of this study was to identify, measure, and estimate the population mortality ratios in Chile, mortality estimates are used to calculate life expectancy when constructing life tables. The Bayesian approach, specifically through Approximate Bayesian Computation (ABC) is employed to optimize parameter selection for these calculations. ABC corresponds to a class of computational methods rooted in Bayesian statistics that could be used to estimate the posterior distributions of the model parameters. For this research, ABC was applied to estimate the mortality ratios in Chile, using information available from 2004 to 2021. The results showed heterogeneity in the results when selecting the best model. Additionally, it was possible to generate projections for the next 10 years for the series analysed in the research. Finally, the main contribution of this research is that we measured and estimated the population mortality rates in Chile, defining the optimal selection of parameters, in order to contribute to creating a link between social and technical sciences for the advancement and implementation of current knowledge in the field of social structures.
