One simple but powerful application included in Options Analysis is analysis of each option's impacts on the remaining options in a selection set.
The analysis involves a comparison of differences of share, advantage and disadvantage between the full selection set and selection sets minus each option, in turn.
In the following example, the first four lines of data in each table below show the results for basic analysis of share, advantage and disadvantage. The first line in each table is for the full selection set of three options. Each of the next three lines in each table are analyses which each exclude one of the three target options. Analysis involves comparison of each of these lines with the full analysis results.
Used here are three appeal measures (using what the US NES calls a "feeling thermometer") for the three main presidential candidates, for the full sample, regardless of whether they voted.
The analysis is based on 1996 US NES data described in the ExampleSample.xls file included in the Options Analysis download package. The actual example is included amongst the analyses contained in the ExampleAnalysis.xls file also included in the download package. In addition to the output example is an Excel version of the analysis where you will be able to see the cell formulas used for calculating the comparative results.
|Impacts of options on shares|
|Shares for reduced selection sets|
|Impact of option in share points|
|Sources of option share|
|Impacts of options on advantage|
|Advantage for reduced selection sets|
|Points change in advantage|
|Percent change in advantage|
|Impacts of options on disadvantage|
|Disadvantage for reduced selection sets|
|Points change in disadvantage|
|Percent change in disadvantage|
If no appeal data is available or you are only interested in share data or you have only choice or probability data for options, then the Option Impacts Analysis package will be more appropriate.
