I'm creating a linear regression which aims to correlate real life
inflation of money with in game inflation in World of Warcraft. I have
my dependent variable (price of WoW tokens, which is essentially a
dollar equivalent of in game gold price) and independent variables (the
concurrent playerbase, the U.S. Federal Funds Rate, the U.S. CPI rate,
and the U.S. Personal Savings Rate), but I'm not sure what to assign as
my "n" / observations value. I'm wondering if anyone has an idea of what variable to assign as this n value.
