It is perhaps compounded of both rhythmic and random elements. Perhaps this time series does not contain a cyclic element. Regression analysis is a statistical method that considers the form of the relationship between two or more variables. Scatter diagrams and regression lines are commonly used to chart the relationship between two magnitude variables, neither of which is plotted at evenly spaced intervals. This equation was not used in our analysis and will be explained in the results.
Regression analysis relies on five assumptions in order to be successful.
The geographic variations in the distribution of the dependent variable is to describe those variations as precisely as possible by portraying them on a map. The first step was obtaining all the necessary data for research. The City of Austin Police Department provided crime data in order to create a database for the years 1980 through 1994. A fifteen year crime index as well as an indexed and non-indexed offenses by census tract spreadsheet were obtained. The data spreadsheets were categorized by indexed crime due to their seriousness and the frequency with which they occur in the city of Austin limits.
