Long Memory Cointegration in the Analysis of Maximum, Minimum and Range Temperatures in Africa: Implications for Climate Change

This paper deals with the analysis of temperatures in a group 36 African countries. By looking at maximum, minimum and range (the difference between maximum minimum) using long memory model based on fractional integration cointegration, we first show that all series display pattern, significant positive time trend 29 countries for 33 ones. Looking range, estimated value order is smaller than one or 17 Performing cointegration tests temperatures, our results indicate two cointegrate classical sense (i.e., short equilibrium relationship) 11 countries, there another eight displaying sense. The remaining no evidence are therefore very high risk climate change due to absence long-term co-movement their temperatures. Findings this tremendous interpretations relevance projections Africa.
