.hi-turquoise[**Description:**] Want to estimate a few coefficients: `\(\beta_0, \beta_1, \beta_2\)`.
- Focus on showing relationships among a few variables: `\(\color{#6A5ACD}{\hat{Y_{i}}}, x_{0i}, x_{1i}, x_{2i}.\)`
- Give up goal of *correctly* modeling the true DGP. Just show patterns as they are.
