Hi everyone.
I use Grouping analysis to create 4 groups from my data.
After that, i use Model Builder to explain that.
However one of my fields keeps returning "ERROR 000906: Zero Variance: All of the values for your input are likely the same." like the picutre.
Any idea why this is happening and is there a way to fix it? Thanks everyone for taking the time.
I would add a model step to copy feature on your selection so you can see exactly what the input to the second tool looks like. It looks like you're not getting the data you want selected on the first ModelBuilder iteration.
Hi Chinh Dang,
You can click the hyperlink for the error to read more information. This error likely means one of your Dependent or Explanatory variables are all the same value. Is this the case?

Hi Lynne Buie and thanks for your answer.
The Exploratory Regression tool will not be able to compute a result with a single feature. You can't model the relationship between the variables with only a single data point. If possible, you might want to adjust the parameters of your Grouping Analysis so your groups have a more reasonable number of features. You can read more about regression at this ArcMap documentation page.
