Mathematical Perspectives on Consumer Spending during a Financial Crisis

AppliedMath
This paper explores the mathematical dynamics of consumer spending during a financial crisis using opponent process theory (OPT). Traditionally applied in psychology, OPT explains how initial emotional responses are followed by counteracting reactions to

Logistic model for forecasting the growth of Ukrainian dairy exports [PDF]

BIO Web of Conferences
A logistic model has been proposed for forecasting the growth of Ukrainian dairy exports. The model takes into account the growth rates of consumption, imports, and domestic production of the importing country. It can be considered a decision-making tool

Inflection and stability points of diphasic logistic analysis of growth

Scientia Agricola, 2015
Growth functions with inflection points following a diphasic model, can be adjusted by two approaches using segmented regression or the sum of two functions. In both cases, there are two functions, one for each phase, with inflection and stability points.

Planktic foraminiferal diversity: logistic growth overprinted by a varying environment

Acta Biológica Colombiana, 2016
This study statistically assesses the relationship between the planktic foraminiferal long-term diversity pattern (~170 Ma to Recent) and four major paleobiological diversification models: (i) the ‘Red Queen’ (Van Valen, 1973; Raup et al., 1973), (ii ...
