Consider f (x)= xn+1 +xn −1. Note that f (0)= −1. Now, since limx→∞f (x)= +∞ there exists a> 0 such that f (a)> 0. Since f is continuous in [0,a] it follows from Bolzano's ... lim−∞f = +∞ and lim+∞f = −∞ so your function has no global min or max.

F U ( u) = n ∫ 0 θ f ( x) [ F ( u + x) − F ( x)] n − 1 d x. Where U = X ( n) − X ( 1), f ( x) is the PDF of U ( 0, θ) and F ( x) is the CDF of U ( 0, θ).

Therefore, x = y x = y or x = −y x = − y. The former works regardless of n n 's parity; the latter works with nonzero variables for even n n only, since if n n is odd (−x)n = −xn ( − x) n = − x n.

If 0 < x ≤ 1, then fn(x) = 0 for all n ≥ 1/x, so fn(x) → 0 as n → ∞; and if x = 0, then fn(x) = 0 for all n, so fn(x) → 0 also. It follows that fn → 0 pointwise on [0,1]. This is the case even though maxfn = n → ∞ as n → ∞.

L ( p) = p ∑ x i ( 1 − p) n − ∑ x i. Now, in order to implement the method of maximum likelihood, we need to find the p that maximizes the likelihood L ( p). We need to put on our calculus hats now since, in order to maximize the function, we are going to need to differentiate the likelihood function with respect to p.Explanation: lim x→∞ (1 − 1 x)x has the form 1∞ which is an indeterminate form. We will use logarithms and the exponential function. So we will investigate the limit of the exponent.
