OLS regression is based on several assumptions which, if violated, may render the results unreliable. The most important assumptions are independence, homoscedasticity, and normality of residuals. Independence of residuals assumes that residual of one observation is independent from residual of another observation.

OLS estimation has some assumptions that must be met for the results to be valid. These assumptions include linearity, independence, homoscedasticity, and normality. Violations of these assumptions can lead to biased and inconsistent estimates.

Using our simulated data set called dat, we want to estimate the regression y on x and z. Since we are calculating by hand, the easiest representation comes by using linear algebra. Therefore, the first step is to get our data into matrix form. We do that in R as follows: y <- as.matrix(dat[, "y"])x <- as.matrix(dat[, c("x","z")])

Derivation of OLS Estimator In class we set up the minimization problem that is the starting point for deriving the formulas for the OLS intercept and slope coe cient. That problem was, min ^ 0; ^ 1 XN i=1 (y i ^ 0 ^ 1x i)2: (1) As we learned in calculus, a univariate optimization involves taking the derivative and setting equal to 0.3.
