Dear all,
I wonder if any one knows if there is an alternative command that can do the same things as "mean" does, but allowing for the use of factor variables.
For example, Im looking forward to do something like this:
Code:
sysuse auto, clear
*This is allowed
mean price
* But this is not
mean c.price
* Much less this
mean c.price#c.price

* It seems, however, that this is allowed:
sum c.price#c.price
* And this:
sum c.price##c.price
Thank you in advance.
Fernando
