what is not a linear regression equation example

Regression allows you to estimate how a dependent variable changes as the independent variable(s) change. Linear regression models use a straight line, while logistic and nonlinear regression models use a curved line. Regression models describe the relationship between variables by fitting a line to the observed data.

The value of the dependent variable at a certain value of the independent variable (e.g., the amount of soil erosion at a certain level of rainfall).

How strong the relationship is between two variables (e.g., the relationship between rainfall and soil erosion).You can use simple linear regression when you want to know: Simple linear regression is used to estimate the relationship between two quantitative variables. With every unit of increase in X, y decreases by m.Simple Linear Regression | An Easy Introduction & Examples Similarly, the value of m can also be a negative value which simply means a negative correlation between X and y. The value of c in some cases can also be negative and it should not be confused as the minimum value of y with no independent variables in the picture. Please Note: These statements are not always practically true in all cases but the logic stands true. For example if we are trying to find a linear relationship between Years of Experience and Salary, the minimum Salary that the company offers despite the years of experience will be a constant value c. This means that even when there is no X present at for the equation, a minimum of c on the y axis can be attained.

Once we find m, we will calculate the value of c which is the constant value at y-intercept.

This shows a correlation between X and y. This simply means that for a single unit change in x, y will change by m.

We will now proceed to find m which is the slope for the line also known as the coefficient.
