Factor Analysis

Factor Analysis Model Parameter Estimation Maximum Likelihood Estimation for Factor Analysis Suppose xi iid˘ N( ;LL0+ ) is a multivariate normal vector. The log-likelihood function for a sample of n observations has the form LL( ;L; ) = nplog(2ˇ) 2 + nlog(j n1j) 2 P i=1 (xi ) 0 1(x i ) 2 where = LL0+ . Use an iterative algorithm to maximize LL.
