I'm trying to take the natural log, $\ln (l (\theta))$, but i'm not sure how this works with respect to $\prod$.Does anyone know what the process for this log is?At first i thought this was the same as taking a cartesian product, but he used the usual $\prod$ symbol for that further down the page, so i am inclined to believe there is some difference.Does anyone …Devops engineers are those who are good at debugging, troubleshooting, analyzing prod issues and providing solutions.Who have good hands on technologies like unix shell scripting, perl, sql etc.
