| nsmwaura | Type 1 error...reject the null hypothesis while its true |
| quanttrader | heteroskedasticity implies more distrib amongst the error term -- ie std error increases, hence t value will increase causing us to reject the null when it may indeed be true (ie type 1 error-- falsely assuming a sign relationship) |
