QUESTION
I run the following program and a typical console output is as follows.
Mean percentage points for weighting 0 is: 57.935590153643616
Mean percentage points for weighting 1 is: 42.06440984635654
Why are these printed means not much closer to 60 and 40?
...ANSWER
Answered 2017-Sep-25 at 16:53You are estimating 100*E(X/(X+Y)]
and 100*E(Y/(X+Y)]
where X = 60*U(1,10)
and Y = 40*U(1,10)
(where U(1,10)
is the discrete uniform distribution on 1,..,10). Since there are only 10*10 = 100 possible ways to generate two such uniform variables, you can compute the expressions for each such pair and then compute these expectations directly. In Python define:
QUESTION
Below are my codes to generate random numbers based on user-defined weighting values. It all works, until I tried to make the type of data become any types, e.g. double, float. I have little experience implement them in practice, only read about them on textbooks. Can anyone helps me fix it?
Thanks,
