Question

What is a linear regression analysis? What does it provide you? Your answer should address development of a linear response equation and associated uncertainty in prediction.

Answer 1

solution :

linear regression analysis :

In insights, direct relapse is a straight way to deal with displaying the connection between a scalar reaction (or ward variable) and at least one logical factors (or free factors).

The case of one explanatory variable is called simple linear regression.

For more than one explanatory variable, the process is called multiple linear regression

Linear regression has many practical uses. Most applications fall into one of the following two broad categories:

On the off chance that the objective is expectation, or guaging, or mistake reduction,[clarification needed] direct relapse can be utilized to fit a prescient model to a watched informational collection of estimations of the reaction and logical factors. In the wake of growing such a model, if extra estimations of the logical factors are gathered without a going with reaction esteem, the fitted model can be utilized to make a forecast of the reaction.

On the off chance that the objective is to clarify variety in the reaction variable that can be ascribed to variety in the illustrative factors, direct relapse examination can be connected to evaluate the quality of the connection between the reaction and the logical factors, and specifically to decide if some logical factors may have no straight association with the reaction by any means, or to distinguish which subsets of informative factors may contain excess data about the reaction.
