$\begingroup$ I prefer $\

**max**\{f(x_1,\ldots,f(x_n)\}$ with curly braces and no parentheses. In this instance, the parentheses don't actually help, and the curly braces remind you that the thing whose maximum is sought is a set rather than a tuple. $\endgroup$21 de ago. de 2011 · M (x) is a function. Taking the maximal number amongst the parameters.

**max**{x1, x2} = {x1, if x1> x2 x2, otherwise. You can define like that the maximum of any finitely many elements. When the parameters are an infinite set of values, then it is implied that one of them is maximal (namely that there is a greatest one, unlike the set {− 1 n ...Stack Exchange Network.

11 de mai. de 2020 · But let's take x = 2, then (1 - 2) ^ 2 will be (-1) ^2 which is nothing but 1 and according to op's

**max**function, 1 should be returned. But since you gave the condition of x >= 1, we always return 0 even when x is something like 2. I think in comments what Andre Holzner said is correct.19 de set. de 2017 · Since composition of convex functions is convex, we only need to show

**max**(x, y) is convex. But**max**(x, y) = x + y 2 + | x − y 2 | and | ⋅ | is obviously convex. A function f: Rn → R is convex if and only if its epigraph epif = {(x, t) ∈ Rn × R ∣ f(x) ≤ t} is a convex set.A general result called Von Neumann-Fan minimax theorem states the following: Theorem 2 (Von Neumann-Fan minimax theorem). Let X and Y be Banach spaces.Let C ⊂ X be nonempty and convex, and let D ⊂ Y be nonempty, weakly compact and convex. Let g: X × Y → R be convex with respect to x ∈ C and concave and upper-semicontinuous with ...

4 de out. de 2018 · Most textbooks will then say that the maximum likelihood estimator of θ is ˆθMLE = X (n). Note. Technically, the above result is false. The MLE does not exist, because θ cannot take on the value x (n) itself. For this answer to be correct, the support of the uniform PDF must include θ itself (because the maximum likelihood estimator equals ...
