Hello,

I have a related question. I am trying to better understand the differences between a few weight options.

I have a similar contrast in which I originally specified

1*happy 1*sad -2*neutral (emotion - neutral contrast is the goal)

Would it be equally correct to do

1*happy 1*sad -1*neutral

if the weights do not need to add up to zero?

I tried it out to see if the results were the same and they were quite different, so I wanted to understand what is happening that is different between these two.
If the desired contrast is emotion> neutral, which model weighting strategy would be more accurate to ask that question?

Thank you!
