Gamma distribution problems and solutions
WebThe basic idea behind this form of the method is to: Equate the first sample moment about the origin M 1 = 1 n ∑ i = 1 n X i = X ¯ to the first theoretical moment E ( X). Equate the second sample moment about the origin M 2 = 1 n ∑ i = 1 n X i 2 to the second theoretical moment E ( X 2). WebSolution. (1) Let f: X!R with R X jf(x)jqdx<1. Let 1 r qso that q=r 1.
