Change cutoff
I am running a linear regression model with 15 attributes. The model accuracy is about 72% with sensitivity of 37%. Is there an operator which can slide the cutoff from 0.5 for the output variable. I want to change the cutoff to 0.4 for predicting variable.

Hi,
The operators you search are called Create Threshold and Apply Threshold.
I can also recommend Optimize Threshold which is part of Operator toolbox extension. It automatically tunes the confidence threshold (aka cutoff) for optimal accuracy. With Optimize Threshold (Subprocess) you can even use another performance measure.
