Describing line of best fit
WebOct 6, 2024 · The equation of the line of best fit is y = ax + b. The slope is a = .458 and the y-intercept is b = 1.52. Substituting a = 0.458 and b = 1.52 into the equation y = ax + b gives us the equation of the line of best fit. y = 0.458x + 1.52 We can superimpose the plot of …

WebThe NLFit tool includes more than 170 built-in fitting functions, selected from a wide range of categories and disciplines. Each built-in function includes automatic parameter initialization code that adjusts initial parameter values to your dataset (s), prior to fitting. Can't find a suitable fitting function in the built-in function library? Web577,1830. Check the Show Line of Best Fit box to see a linear approximation of this data. The correlation coefficient ( r) indicates how well the line approximates the data. If r = 1, the line is a perfect fit to the data; if r = 0, the line does not fit the data at all. In general, the closer r is to 1, the better the fit.
