weka M5Prime Output

[larrymckay]

How would you interpret the following output of the M5Prime Algorithm?
What does the 1:0 mean in the actual and predicted columns?

inst# actual predicted error prediction (EDi)
78 1:0 1:0 1 (6)

Which version of Weka are you using? In the current developer version 3.5.6, the output for a regression scheme looks like:

inst#, actual, predicted, error
1 0.2 0.238 0.038
...

Cheers,
Mark.
