Polyfit in python
WebPython has methods for finding a relationship between data-points and to draw a line of linear regression. We will show you how to use these methods instead of going through the mathematic formula. In the example below, the x-axis represents age, and the y-axis represents speed. Web1. The equation y = mx + b of best fit for this set of points can be found using the NumPy library. To calculate the coefficient m and constant b, we need to find the best-fit line for the data points. To do this, we can use the np.polyfit() function. This function takes two arguments: an array of x values and an array of y values.
