The key to curve fitting is the form of the mapping function. A straight line between inputs and outputs can be defined as follows: y = a * x + b. Where y is the calculated output, x is the input, and a and b are parameters of the mapping function found using an optimization algorithm.find all the points within those boundaries. add a line using those points. if the line is too thick or not continuous, adjust the boundaries and repeat. determine the value that delineates inside or outside - maybe .08 percent. use numpy's .isclose method, with an appropriate tolerance, to find the points close to that value. 3. Calculate the y-intercept (b) using the following formula: b = mean (y) – m * mean (x) 4. Determine your line of best fit using this equation: y = mx + b. Now you have your line of best fit equation, which you can use to draw a trend line on your scatterplot or make predictions based on x values. Nov 21, 2023 · The line of best fit formula is y = mx + b. Finding the line of best fit formula can be done using the point slope method.
