There are certain qualities that you want to be present in the place that you choose to live in. For years businesses have had ways of developing similar areas (typically called clusters or enclaves.) EASI products allow the creation of a similar type of grouping, but adds to the census variables a collection of data that affect where people want to live. Variables like Crime, Weather, Amusement, Culture, etc.
Index Numbers are statistically important to estimates. It is essential to understand that there are no units needed with an index number. That is, you don't have to be concerned with income being in thousands of dollars, weather being in average annual rainfall, or population being in units. The variables that EASI products use are sometimes percentages with a range of 0 to 1, sometimes rational (zero to infinity,) or sometimes averages with a limited range of estimates.
Ranking has been essential to the development of the analysis used in EASI products. Within the products, the results based upon ranking will be correlated to the results based upon other types of statistical analysis.
Intensity Index – The EASI Intensity Index is a measure that shows two important characteristics. First this measure shows the strength of the results. An Index of 100.0 indicates that for the values chosen for weights, this geography was ranked the highest possible for those values. A value of 0.0 indicates the lowest possible values for the chosen variables. In addition, users can judge how similar each geography is to another. Geographies can be ranked next to each other, but the Intensity Index may show a large drop compared to the next geography. The Intensity Index is used in the Similar Reports & Analysis and in the User Profiles & Analysis.
The variables can be both discrete and continuous. Continuous variables are not restricted in any way, while discrete variables are restricted to their outcome. The EASI products are going to develop an analysis of the index numbers which will be ranked based upon estimates. In all EASI products, the variables will normally be described by the different ranges they might have.
The philosophy of EASI is to make the numbers work for the user and to prepare the numbers so that they are ready for any analysis. This data preparation is essential to get the EASI products to work the way we wanted. By indexing and ranking all of the results, we capture what makes the particular selected geography special. Through indexing and ranking we can accommodate all kinds of data. For example:
· Are there 5 times more children than expected?
· Is this area of moderate income?
· Are they really as concerned with education as we are?
· Is the weather going to be okay?
· Are there enough job opportunities?
· Is the area safe?
By carefully combining all of the variables that are important to you, you will be able to find a great area to live in, one that matches your needs and desires. You must first develop two lists of variables, one of variables that have a strong positive influence and the other of variables of strong negative influence on your selection process. Begin by going through our list. We suggest beginning by picking just one variable, and then moving on and picking from 5 to 20 additional variables. We've also seen people choose 100 variables and create special areas for themselves. Try ranking the variables in a certain order. You can, of course, try several different types of neighborhoods. Ranking the variables is very important and will allow you to really develop special results. You should carefully review all of the choices first, make some notes on what is best for you, and then move on to the actual data processing and selection.
After ranking, the best way to ensure special results is to really search and review these variables and see if there are some make or break variables. Of the 5 variables chosen how much more important is the first compared to the second? (Remember that when ranking with five variables, number 1 gets a weight of 5 and number 2 in rank gets a weight of 4 and so on.) By providing your own weights you can determine the exact importance of each variable - who is better qualified to determine your own needs and values than you?
However, weights should not be a cause for concern. Here are some hints:
Arrange the variables in rank sequence. Assign a weight of 10 to the most important variable; then choose a smaller and smaller weight by directly comparing each variable to the one just above it in importance. Therefore, the next variable can be given a weight less than 10. If the variable is almost as important call it 9.999 or 9.5. If it is half as important in your mind, make it a 5. Do the same for each succeeding variable until you have assigned a weight to every variable (lower limit is any number greater than 0.)
Another way to assign weights in a family is to have everyone choose the variables and then each can choose a weight and average the in-house results.
Or of course you can try several different weights and see what different results you get.
The key to success is picking the variables that are important to you - now or for your future plans. You can play games with your present thoughts, figuring out where to live when you are single, when you are married, when your kids have grown up and left home, or maybe when you retire.
