Zastosowanie modeli ARIMA w badaniach nad stresem ekonomicznym wpływającym na kondycję biologiczną populacji ludzkich
Streszczenie
The research on the relations between economic stress and the value of secondary sex ratio
(SSR) was initiated by Trivers and Willard (1973). The seminal study in this field speculated that
smaller (than needed) consumption of goods and services might sufficiently stress human populations
and make the secondary sex ratio lower.
In order to verify the hypothesis that the observed time-series of secondary sex ratio (SSR) in
Poland is declining with the deterioration in „economic conditions”, the ARIMA mathematic
model of both analysed phenomena (according to the statistical procedure proposed by Catalano
and Bruckner (2005)) was constructed. The analysis is an attempt to answer the question: if the
statistically important decline of SSR in Poland after the Second World War was an effect of
deterioration of economic condition.
