i'm learning the method of moments and i'm not understanding on how to do it. so for example, fy(y, theta) = theta*y^(theta -1). 0<=y<=1. to find the method of moments estimate for theta. the book does E(y) = the integeral from 0 to 1 of y * theta*y^(theta-1) dy. and that becomes theta * y^theta+1/theta + 1 and that becomes theta/ theta + 1..... first question. am I really suppose to integrate y * theta*y^(theta-1) dy? first of all, the book has never gone to any of the harder integration techniques, and i really have trouble integrating this. how did they do the steps??
