Weight of specific group of data in whole datasetIn the image attached, I am trying to find out or rather calculate weight of the set of variables in circle in (A). When it is included in the data set it gives an R-sq of 0.59, however, when it is excluded the coefficient reduces to the minimum (B).
How can give a weighted value to the dataset, as I would like to exclude it from the dataset while showing and explaining on valid reasons why it is excluded?
AnalyticsData TableWindowsRe: Weight of specific group of data in whole datasetIf I correctly understand what you want to do, all you have to do, is to go to the graph and drag and select the data values in question, and then right click on one of the selected points and in Graph Builder or Fit Y by X
Rows=>Hide and Exclude
Re: Weight of specific group of data in whole datasetOther guess depending what you mean with the weight / exclusion:
Using big class as an example:
Red points are the ones I want to exclude from analysis (but still how them):
R2 = 0.559
Select them and just exclude (don't hide):
They will disappear from graph builder:
R2:0.351
Now HOLD SHIFT while clicking red triangle and it will show you hidden options (why are these hidden and are there more hidden options / list of hidden options some where?) (found from here). The excluded rows should be shown a bit transparent
R2:0.351
