Ex 2:Adaptive Models in Decision Strategy: Smooth Propensity always 0

Hi,

At the end of this exercise my Smooth Propensity is always 0 so I'm guessing I didn't set the property correctly:

Here's my Set Property:

The expression used is:

((.StartingEvidence/(.StartingEvidence + .ModelEvidence+1))* .StartingPropensity) +((.ModelEvidence/(.StartingEvidence + .ModelEvidence+1))*.pyPropensity)

Which was cut and pasted directly from the exercise guide (unfortunately you can't see the whole of the expression used in the solution video).

ModelEvidence is 2.0

pyPropensity is approx 0.83

What did I do wrong?

 

Regards,

Rob
