Comparing the Gompertz-Type Models with a First Passage Time Density Model

  title={Comparing the Gompertz-Type Models with a First Passage Time Density Model},
  author={C. Skiadas},
In this chapter we derive and analyse Gompertz-type probability density functions and compare these functions to a first passage time density function. The resulting Gompertz-type pdfs are mirror images of each other, each skewed in a specific direction, whereas the first passage-type model gives functions with both left and right skewness depending on parameter values. We apply these pdfs to the life table data for females in the United States, 2004, and to the medfly data provided in Carey et… Expand

Parameter identification for gompertz and logistic dynamic equations
This paper generalize and compare Gompertz and Logistic dynamic equations in order to describe the growth patterns of bacteria and tumor, and notices that Logistic curves are better in modeling bacteria whereas the growth pattern of tumor is described better by GOMpertz curves. Expand
A family of stochastic differential equation (SDE) models is derived and studied for the aging of biological organisms. The SDE aging models give meaningful mathematical interpretations of the agingExpand
Exploring the State of a Stochastic System via Stochastic Simulations: An Interesting Inversion Problem and the Health State Function
Weexplore a method for finding the State H(t) of a Stochastic System when the first exit time or hitting time probability density function g(t) is given. The task is to find an analytic form for theExpand
Skew-t fits to mortality data--can a Gaussian-related distribution replace the Gompertz-Makeham as the basis for mortality studies?
Results showed skew-t fits to Human Mortality Database data obtained lower Bayesian information criterion values than Gompertz-nested distributions, applied to low-mortality country data, including 1711 and 1810 cohorts. Expand
Life Expectancy, Deterioration Function and Application to Halley Breslau Data
Further to the proposal and application of a stochastic methodology and the resulting first exit time distribution function to life table data we introduce a theoretical framework for the estimationExpand
Properties of a Stochastic Model for Life Table Data: Exploring Life Expectancy Limits
The model is used to estimate the development of mortality rates in the late stages of the human life span, to make better fitting to population mortality data including the infant mortality, to compare it with the classical Gompertz curve, and to make comparisons between the Carey med-fly data and the population mortalityData estimating the health state or "vitality" functions.

The First Exit Time Theory Applied to Life Table Data: The Health State Function of a Population and Other Characteristics
In this article, we summarize the main parts of the first exit time theory developed in connection to the life table data and the resulting theoretical and applied issues. New tools arise from theExpand
Life Expectancy at Birth, Estimates and Forecasts in the Netherlands (Females)
In this chapter we explore the life expectancy at birth in the Netherlands based on a recent theory and a new methodology but also a classical theory of fitting and forecasting. We use the data fromExpand
Timescales and Error Estimates in Dynamical Systems
This note indicates where one can obtain an advantage from the concept of timescales and presents examples from bifurcation theory where the anticipation of timesCales is not straightforward and multiple timing is in danger of being decient. Expand
A Life Expectancy Study based on the Deterioration Function and an Application to Halley's Breslau Data
A theoretical framework for the estimation of the maximum deterioration age and to explore on how "vitality," according to Halley and Strehler and Mildvan, changes during the human lifetime is introduced. Expand


A Modeling Approach to Life Table Data Sets
A modeling approach to Life Table Data sets is proposed. The method is based on a stochastic methodology and the derived first exit time probability density function. The Health State Function of aExpand
First exit densities of Brownian motion through one-sided moving boundaries

Benjamin Gompertz showed that if the average exhaustions of a man's power to avoid death were such that at the end of equal infinitely small intervals of time, he lost equal portions of his remaining power to oppose destruction, then the number of survivors at any age x would be given by the equation.

A stochastic model of aging is proposed to explain deviations from exponential growth in mortality rates commonly observed in empirical studies and simulations of populations with age-dependent distributions of viabilities agree with a wide array of experimental results. Expand
Dynamic modelling of life table data
A dynamic model expressing the human life table data is formulated by using the firstpassage-time theory for a stochastic process and the results derived for pension funds and option theory are discussed. Expand

Slowing of mortality rates at older ages in large medfly cohorts.
The results cast doubt on several central concepts in gerontology and the biology of aging: that senescence can be characterized by an increase in age-specific mortality, that the basic pattern of mortality in nearly all species follows the same unitary pattern at older ages, and that species have absolute life-span limits.
