hi guys can someone plz help me with this:
I am running a regression model: WeightedRedRt is my dV, and AgeMonthlyGrouped, Incentive, and SQUAREDIncentive are my IV's. The regression runs fine. But, when I add an additional filter to my data (AgeMonthlyGrouped < 2), I get the following warning message: Any idea what this means? After filtering, I still have 141 cases so I'm confused why this message would appear. Thanks! Warnings For models with dependent variable WeightedRedRt, the following variables are constants or have missing correlations: AgeMonthlyGrouped. They will be deleted from the analysis. |

You probably only have one value of AgeMonthlyGrouped within your 141 cases.
Run a descriptives on your filtered data and look at the maximum and minimum values to check this. If so, there is nothing you can do. A constant cannot predict anything, or correlate with anything.
