### GeNIe:Hybrid Models Heat Equations Autodiscretized Hybrid example

Hi,
I am trying to understand the output in Temperature Air outside node .
Toa=Choose(Season,Normal(10,5),Normal(25,5),Normal(10,5),Normal(0,5))
https://youtu.be/dyg7RFQhPTw?t=290

Toa=Choose(Season,Normal(10,5),Normal(25,5),Normal(10,5),Normal(0,5))
Question 1 : Does the above equation mean, depending on the Season variable choose form corrosponding Normal? i.e Spring =100% the first Normal(10,5) etc , if season = Summer =100% then second normal = Normal (25,5)? if then what does it do when each is set to 25%?

Question 2: When I set any attribute in the Season node to 100% why does it always return -2.5( For example spring 100% or Summer or Fall anyone) ?

Hi,

I will be happy to help. When the Season is not observed, you get a mixture of Gaussians in the node Outside Air Temperature, weighted by the probabilities of the four seasons.

I can see in the picture that you must have observed a value -2.5 in the node Outside Air Temperature (there is a grounding symbol in that node). Please release that observation and you will get the marginal distribution displayed in the node.

I hope this helps,

Marek
