In order to determine whether time series Y, contains a unit root, the following regression has been estimsted by OLS for asample of 100 observationsAY,0.49-0.12Y,-+0.54AY,.where the numbers in parentheses are standard errors and where the number of lags was selected using the Bayes informationcriterion (BIC). Does the series Y, contain a unit root? Explain your answer. Write your explanation in the box below

Unit root tests are tests for determining the stationarity property in the model of time series.…

An electroencephalogram (EEG) is a tracing of brain waves recorded by an electroencephalogranh Neurologists have found that the peak EEG frequency in normal children increases with age in Ph. study (reported in Science, 1982), 287 normal children ranging from 2 to 16 years old were instructed to hold a 65-gram weight in the palm of their outstretched hand for a brief but unspecified time The peak EEG frequency (measured in hertz) was then recorded for each child. The children we grouped according to age, and the average peak frequency for each age group was recorded. The data appear in the accompanying table.
