compute simple linear regression equation

With every unit of increase in X, y decreases by m. Similarly, the value of m can also be a negative value which simply means a negative correlation between X and y. Use correlation analysis to determine whether two quantities are related to justify fitting the data. 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. Perform simple linear regression using the operator. 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. another way of thinking about the n-2 df is that its because we use 2 means to estimate the slope coefficient (the mean of Y and X) df from Wikipedia: '. 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.
