Listen I know we need a lot of variables in math. A single alphabet won’t due. So capital and lower case letters can be different variables. I can even roll with the idea that letters of the same case in different *typefaces* can be distinct— but, I still find the abusive use of C in Hoggs Mathematical Statistics a little extreme… we couldn’t get more distinct typefaces? How many students have cried because you did this, Hogg? (i otherwise love this textbook it’s so much fun) /math rant
