WebMar 20, 2014 · When you differentiate h, you are not finding the derivative of the concrete value of h (x) (which in your case was h (9)=21). Instead, you are finding the general derivative for the whole function h, and then you plug in your x value of 9 to solve. So the derivative of h (x) is h' (x)= 3f' (x)+ 2g' (x). Then if we need h' (9), we solve:

WebAn antiderivative of function f(x) is a function whose derivative is equal to f(x). Is integral the same as antiderivative? The set of all antiderivatives of a function is the indefinite … WebAs always, the moment generating function is defined as the expected value of e t X. In the case of a negative binomial random variable, the m.g.f. is then: M ( t) = E ( e t X) = ∑ x = r ∞ e t x ( x − 1 r − 1) ( 1 − p) x − r p r. Now, it's just a matter of massaging the summation in order to get a working formula.

In the two variable case, (,) and (,) are the principal minors of the Hessian. The first two conditions listed above on the signs of these minors are the conditions for the positive or negative definiteness of the Hessian. citizens bank online mortgage

WebIf we take the second derivative of the log-likelihood, we get n ˙2. Since nand ˙ 2 are always positive, the second derivative is always negative.4 For a ﬁxed ˙2, in a function with only one parameter like this one, a negative second derivative is sufﬁcient for the likelihood to be convex.5 As a result, this model is not multi-modal. WebFeb 26, 2016 · A final word: perhaps the most elegant computation is to exploit the fact that the negative binomial distribution is a generalization (i.e., a sum of IID) geometric random variables. But the purpose of this answer is to show how the computation can be done purely as an algebraic manipulation with very few prerequisites.
