His notation worked perfectly for him but was unreadable for others. I can’t imagine writing expressions in any other way! Turns out, there are other ways. Infix, Prefix, and Postfix expressions Our standard notation is called infix. We use parenthesis...

For my linear regression class, I misheard that we had to do the variance analysis without any built-in or external packages…by hand! so I wrote an analysis of variance class aov_table() and a t-test function meanCI() to test...

We get to choose a problem in any topic and research the current statistical analysis techniques. The goal is relate the techniques back to the topics that we have learned so far. It...

This week, we are doing chapter 5, estimators. If you want a good rundown of MLE, there are tons of other resources at the end of this post. Likelihood Function v....
