2. Random variables X and Y have joint probability density function f(x, y) = kry, 0<<1,0 <y <1. Assume that n independent pairs of observations (C,y:) have been made from this density function. (a) Find the k which makes f(x,y) a valid density function, (b) Find the maximum likelihood estimators of a and B. (c) Find approximate variances for â and B.
Find the absolute extrema of the function on the closed interval. (Order your answers from smallest to largest x, then from smallest to largest y.) f(x) = sin(2x), (0, 2) minimum (x,y) = (x,y) - maximum (x, ) = (x,y) =
Write a function to find the smallest odd number in a list. The function takes a list of numbers (each number is greater than or equal to 0) as an input. The function outputs a tuple, where the first number in the tuple is the smallest odd number and the second number in the tuple is the number of occurrences of that number. For example, if the input is [1, 4, 7, 3, 5, 2, 1, 3, 6] then the...
