It can't be this hard, right? I really need a shove in the right direction
here. Been spinning wheels for three days. Cannot get past the errors.
I'm doing something wrong, obviously, since I can easily compute the Box's
M right there in RStudio
But I don't see what is wrong below with the coding equivalent.
The entire code snippet is below. The code fails below on the call to the
boxM statistic call.
PLEASE HELP!!!
Thanks in advance,
