Significance formula

[Mouchemhou]

Question

Hello,
I am trying to calculate the significance for my signal and Bps with
set main.sbratio = 'sqrt(2*((S+B)*log(1+S/B)-S))'
and I get the error below,
MA5-ERROR: 'main' has no parameter called 'sbratio'

Any comment please?

Best regards,
MO

Hi MO,

The right attribute is fom.formula.

Dear benjamin,
this formula is also not correct,
set main.fom.formula = 'sqrt(2*((S+B)*log(1+S/B)-S))'

and MA5 print out an error like:
AttributeError: 'str' object has no attribute 'str'

Best wishes,
MO

Hi, I can only suggest to read the manual or the reference card in order to understand how this option works. Regards, Benjamin
