WebTry graphing the function y = x^3 + 2x^2 + .2x. You have a local maximum and minimum in the interval x = -1 to x = about .25. By looking at the graph you can see that the change in slope to the left of the maximum is steeper than to the right of the maximum. WebJul 6, 2013 · Many, but not all, likelihood functions we usually encounter have strictly convex logarithm (i.e., they're log-concave). Consequently, they have a unique stationary point and that is the global maximum. This doesn't mean that there might be cases where the likelihood has multiple local maxima. You always look for the global maximum in MLE.
