Goodness Fit Test For Binomial Flashcards
Trying to model if data can fit binomial, and as they haven’t given p, need to estimate our selves. How to do?
Remember eldected number binomial = np= which we estimate as MEAN
- find mean using calculator
- now divide by n which is total NUMBER (not with 0)
- this is p now
And x - B( n, p)
Okay now we need executed frewuencies, how easiest to do so
Probability in a binomial can use calculator, but easiest is prolly manual and switch numbers
Remember p(x=r) = ncr x r ^succes x n-r ^failure
MULTIPLY BY N
Now change r values and you’ll have all expected frewuecies
What is n in these cases
It’s the thing Esch thing is doing , so if Esch hospital doing 30 n is 30
Now remember to do final colour as MAXIMUM TO THE END N
But this time using binomial CD instead of poison
