Expected value in python
WebMar 18, 2024 · Your plot is (at least approximately) correct, the problem is with modeling your data as Poisson. As lambda grows large the Poisson looks more and more like a normal distribution — see this plot from Wikipedia. A Poisson distribution has its variance equal to its mean, so with a mean of around ~240 you have a standard deviation of ~15.5. WebFor discrete random variables, the expected value is the sum of the possible outcomes weighted by their probability. To calculate the expected value, each outcome is …

However, when I run this code, I get the following error: ValueError: not enough values to unpack (expected 4, got 1). I have tried to look for the solutions online (even came across the same question) but I am unable to solve this code.
WebThe valueerror: too many values to unpack occurs during a multiple-assignment where you either don't have enough objects to assign to the variables or you have more objects to assign than variables. If for example myfunction () returned an iterable with three items instead of the expected two then you would have more objects than variables ...
