| Let f(x)=1/6, x=1,2,3,4,5,6, zero elsewhere, be the pmf of a distribution of the discrete type. Show that the pmf of the smallest observation of a random sample of size 5 from this distribution is g1(y1)=((7-y1)/6)^5 - ((6-y1)/6)^5, y1=1,2,...,6, zero elsewhere. Note that in this exercise the random sample is from a distribution of the discrete type. All formulas in the text were derived under the assumption that the random sample is from a distribution of the continuous type and are not applicable. Why? | 2022-12-25 | AA |
