Actual exam question for Databricks's Databricks-Certified-Professional-Data-Scientist exam

Question #: 65
Topic #: 2

[All Databricks-Certified-Professional-Data-Scientist Questions]

Which method is used to solve for coefficients bO, b1, ... bn in your linear regression model:

AApriori Algorithm

BRidge and Lasso

COrdinary Least squares

DInteger programming

Show Suggested Answer

Suggested Answer: C

In the linear model, the bi's represent the unknown p parameters. The estimates for these unknown parameters are chosen so that, on average, the model provides a reasonable estimate of a person's income based on age and education. In other words, the fitted model should minimize the overall error between the linear model and the actual observations. Ordinary Least Squares (OLS) is a common technique to estimate the parameters

Ooh, A) Apriori Algorithm? That's for association rules, not linear regression. C) is the correct answer here.

B) Ridge and Lasso are great options for regularization, but for the basic linear regression coefficients, C) is the way to go.
