Predicting House Prices with Regression Techniques

That straight line from math class can actually predict house prices. It’s called linear

regression, and it’s all about finding the one "line of best fit" for your data,

like house size versus price. The slope of that line literally tells you how much the

price goes up for every extra square meter. You even get a score, R-squared,

to see how well your line explains everything. But what if the data is messy and

doesn't follow a straight line? That’s when you use smoothing. Instead of forcing

one rigid line, it draws a flexible curve that follows the data’s true, wiggly pattern.
