To visualize the trend or pattern in the data, you may need to know how to draw the best fit line. In the below image, the red line indicates the best fit line. What Is the Best Fit Line? The best fit line, also known as a linear regression line, represents the relationship ...
Since cubic regression returns a polynomial with a degree of three, we must find the coefficients for x, x², and x³. Another alternative to finding the cubic regression of a dataset is to use the trendline tool. We’ll use a scatter plot to visualize the shape of our data and use...
