A Competing‐Risk Model for Animal Mortality
TL;DR: A three—component competing—rick model for animal mortality is presented, in which the additive hazards include a new model, dominant during the prematurity period; a constant hazard, dominant During the period of maturity; and the conventional Gompertz hazard, dominates during senescence.

Abstract: A three—component competing—rick model for animal mortality is presented, in which the additive hazards include a new model, dominant during the prematurity period; a constant hazard, dominant during the period of maturity; and the conventional Gompertz hazard, dominant during senescence. A good fit of the model is obtained to survival data for a variety of species, with both laboratory and field data being represented. Interpretation of the model parameters in terms of animal adjustment to hazards is offered. See full-text article at JSTOR

Differences in age-specific mortality between wild-caught and captive-born Asian elephants.
TL;DR: It is shown that captured elephants have increased mortality compared to captive-born elephants, regardless of their capture method, and these detrimental effects of capture are similar for both sexes but differ substantially according to age.

Some Laws of Mortality: How Well Do They Fit?
Timothy B. Gage,Charles J. Mode +1 more
TL;DR: The goodnesses of fit over the entire life span of four models of mortality are compared using life tables from Australia and the United States and it is concluded that the Heligman-Pollard and Mode-Busby models are probably misspecified.

Parametric Survival Analysis Combining Longitudinal and Cross-Sectional-Censored and Interval-Censored Data with Concomitant Information
TL;DR: In this paper, the authors describe a method for analyzing survival data with a generic family of continuously differentiable survival distributions, which can be related by a common differential equation (Turner and Pruitt, 1978).

Status and health in Roman Dorset: The effect of status on risk of mortality in post‐conquest populations
TL;DR: It is found that male mortality risk was higher than females, which is considered to reflect underlying sex-differences in immunity and disease response.

Detecting and inferring cause of change in an Alaska nearshore marine ecosystem
TL;DR: In this paper, the authors describe a monitoring program initiated in 2006 that focuses on the nearshore benthic food web in the Gulf of Alaska, whose design anticipates potential causes of ecosystem change to improve rigor, resolution, and confidence in understanding the mechanisms underlying change.

Theoretical explanation of observed decreasing failure rate
TL;DR: In this article, the authors used the theorem that a mixture of distributions each having a non-increasing failure rate (e.g., a mix of exponential distributions) itself has a non increasing failure rate, and the apparent decreasing failure rate of the pooled air-conditioning life distribution was satisfactorily explained.

An analysis of some failure data
TL;DR: The rationale and statistical techniques employed in the analysis of some failure data obtained from operations performed by machines and people are summarized and the agreement between theory and data is evaluated.
