Instructions for doing time series data analysis.
In this part you can do year-by-year analysis. Seventeen of the 30 time series variables are from the
Regional Economic Information System from the US Dept of
Commerce, while the remaining ones are from the Georgia County Guide.
There are three types of analysis you can perform:
1. See the data. This option will let you look at the raw data, just as they appear in the Georgia
County guide. You can select one variable at a time. The result will show you, for the county you select,
the data points starting at the earliest year.
2. Calculate Means. This will report the averages, standard deviations, the maximum and minimum values.
You can specify one variable at a time.
3. Plot a variable over time. Values of the variable will appear on an X-Y graph.
Seven of the variables from REIS are monetary variables (i.e., dollars) and the time series extend back to 1970.
The variables are:
Farm Income
Farm Receipts, Livestock
Farm Receipts, Crops
Farm Receipts, Govt Payments
Per Capita Income
Earnings per Job
Total Personal Income
During this 30 year time period there has been a considerable amount of monetary inflation. A dollar in 1970
purchased what $4.44 could purchase in 2000. Therefore, the variables from REIS are presented in both nominal and
real terms, with 1982-84 as the base period when the inflation index equaled 100. To learn more
