1 Stationarity and unit Root testing WHy do we need to test for Non-Stationarity? The stationarity or otherwise of a series can strongly influence its behaviour and properties -e.g. persistence of shocks will be infinite for nonstationary series Spurious regressions. If two variables are trending over

CCCma has develped a number of climate simulation models for climate prediction, study of climate change and variability, and to better understand the various processes which govern our climate system. A brief description of these models and their corresponding references can be found in this section

1.The Nuer a. Famous in anthropology long before Hutchinson's book i. The Nuer were pacified by the British colonial forces 1. After their pacification anthropologists could study them 2.

When we talk, we don't talk in single words but in groups of words spoken continuously. These groups of words which are closely connected in meaning and in grammar are called sense groups. sense group is tone-group-(语调群) in intonation. long sentence can be cut up into two or more tone-groups We may make a short pause after each group, but not during the group
