**Linear fit in Matplotlib Examples Plotly**

Todayâ€™s post is about the gradient descent algorithm and how it is used within linear regression. Linear regression is used to find the best fit line (also known as minimizing the â€œlack of fit... To estimate the uncertainty of the best fit one draws two worst fit lines. These indicate the largest and smallest slopes which might still reasonably fit the plot. The uncertainty of the best fit is then taken as half the difference between the worst fits. Note that the best fit â€¦

Hello, I've been told that I have to draw a line of "worst fit" in order to find the percentage uncertainty in the gradient...I understand the process f... Now the question is: What should the slope of this line be? certainly find a line of best fit to the data shown, it would have little meaning. (We might wish to find an exponential or a quadratic curve to fit the data.) If you suspect data fits a curve of the form y ac= x, say, taking logarithms gives log log logy x c a= +, which is a straight line relationship between x logand y. We can p

## How To Find Gradient Of Line Of Best Fit

### 23/04/2008Â Â· Best Answer: Take any two points on the line. Choose the most convenient. The gradient is the slope of the line, which as it's straight, is the same everywhere, and the slope or gradient is the same as the tangent.

- For the line of gradient m the intercept is 31.8 For the line of gradient m 1 it is 30.8 and for the line of gradient m 2 it is 32.7. So the value for the intercept could be quoted as 31.8 +/-1.0.
- I was able to create a â€˜best fitâ€™ line with the final slope and intercept (from your gradient descent algorithm) that matched the â€˜best lineâ€™ fit from running numpy â€˜polyfitâ€™. Thx for the great example!
