I am trying to fit a line on each dataset, but when I check the metrics this is what I get:
- Set 1 (red): R squared=0.002, p-value=0.651
- Set 2 (purple): R squared=0.008, p-value=0.378
- Set 3 (blue): R squared=0.001, p-value=0.714
My question: are such data sets impossible to fit? Is there any kind of data transformation I could apply, based on the scatterplot shape?
The goal is to predict from regression.
