Answers

Answer 1

A regression analysis between sales (in $1000) and price (in dollars) resulted in the following equation y-hat = -0.5x + 800.This equation suggests that for every dollar increase in price, sales will decrease by $0.5 thousand.

Regression analysis is a group of statistical procedures used in statistical modelling to determine the relationships between a dependent variable (often referred to as the "outcome" or "response" variable, or a "label" in machine learning jargon), and one or more independent variables (often referred to as "predictors," "covariates," "explanatory variables," or "features"). In linear regression, the most typical type of regression analysis, the line (or a more complicated linear combination) that most closely matches the data in terms of a given mathematical criterion is found. When using the ordinary least squares method, for instance, the specific line (or hyperplane) that minimises the sum of squared differences between the genuine data and that line is computed (or hyperplane).
