Moment Generating Function Explained - Towards Data Science

WebTo find the variance, we first need to take the second derivative of M ( t) with respect to t. Doing so, we get: M ″ ( t) = n [ 1 − p + p e t] n − 1 ( p e t) + ( p e t) n ( n − 1) [ 1 − p + p e t] n − 2 ( p e t) And, setting t = 0, and using the formula for the variance, we get the binomial variance σ 2 = n p ( 1 − p): WebObjectives. Upon completion of this lesson, you should be able to: To refresh our memory of the uniqueness property of moment-generating functions. To learn how to calculate the … deleted items in sharepoint
