20,000 samples of simulated data. The response values y_i are simulated according to the following:
y_i = 0.76 - 0.92*x_{i1} + 0.64*x_{i2} + 0.57*x_{i3} - 1.65*x_{i4} + ε_i.
Here, each predictor variable is simulated from a Normal distribution with mean = 0 and variance = 1.0, and each ε_i is simulated from a Normal distribution with mean = 0 and variance = 0.25; the predictor variables are assumed to be independent.
