Is this a homework problem? The posting guide linked below explicitly says:

"*Basic statistics and classroom homework:* R-help is not intended for
these."

Hello,
please, I need to calculate the indicator function as I underlined in my
attached pdf file but I can't define a code in programming language that
deals with this case. Please help me with a code whether it's in python or
R can help me.



   Sincerely.
