Reactions to extreme events: moving threshold model [PDF]
, 2005 In spite of precautions to avoid the harmful effects of extreme events, we experience recurrently phenomena that overcome the preventive barriers. These barriers usually increase drastically right after the occurrence of such extreme events, but steadily

HERITABILITY AND BREEDING VALUE OF SHEEP FERTILITY ESTIMATED BY MEANS OF THE GIBBS SAMPLING METHOD USING THE LINEAR AND THRESHOLD MODELS [PDF]
Journal of Central European Agriculture, 2013 The research was carried out on 4,030 Polish Merino ewes born in the years 1991- 2001, kept in 15 flocks from the Pomorze and Kujawy region. Fertility of ewes in subsequent reproduction seasons was analysed with the use of multiple logistic regression ...

Effects of type traits, inbreeding, and production on survival in US Jersey cattle
Journal of Dairy Science, 2023 : Greater longevity is associated with lower replacement costs, higher average milk production, and fewer replacement heifers needed. Longevity data are obtained late in life, and for this reason stayability, defined as the probability of survival from ...

Threshold models for the determination of genetic variability among reproductive traits in Nellore cattle [PDF]
Pesquisa Agropecuária Brasileira: The objective of this work was to evaluate the potential of different threshold models to determine the genetic variability in Nellore cattle, with basis on the heritability estimates for the traits stayability (STA) and first calving probability at 36

Thresholds models of technological transitions [PDF]
Environmental Innovation and Societal Transitions, 2014 We present a systematic review of seven threshold models of technological transitions from physics, biology, economics and sociology. The very same phenomenon of a technological transition can be explained by very different logics, ranging from economic explanations based on price, performance and increasing returns to alternative explanations based on

Contemporaneous-threshold smooth transition GARCH models [PDF]
, 2011 This paper proposes a contemporaneous-threshold smooth transition GARCH (or C-STGARCH)model for dynamic conditional heteroskedasticity. The C-STGARCH model is a generalization tosecond conditional moments of the contemporaneous smooth transition ...
