Hi, I would like to double check if the question imply X~gamma(beta = 0.05, gamma = 5 (instead of 20)) which would then be equvalent to the answer saying X ~ gamma (alpha = 5, lambda = 20) and the answer can be derived respectively. right? YY
Hi. Yes, unfortunately Sweeting and the Tables use slightly different notation. alpha = gamma lambda = 1/ beta So, Gamma(alpha=5, lambda=20) is correct
Can someone confirm that in an exam situation we won't need to remember how to convert the sweeting notation to the notation used in the tables??
We would hope that the examiners use the notation in the Formulae and Tables, but unfortunately there are different notations out there so best to take care rather than blindly apply a formula.
