One part of analyzing data that is frequently useful is where we have some set of data and a model to which we believe it corresponds. Then, we can have Mathematica find a fit for the data based on the model. For an example of how this works, let’s sample points from \((x-2)^2-1=x^2-4x+3\), then have Mathematica fit this (incorrectly) to …

NettetFit is also known as linear regression or least squares fit. With regularization, it is also known as LASSO and ridge regression. Fit is typically used for fitting combinations of … NettetLooking at your data-points there seems to be something like a straight line at the right and left end. Get some of the first and some of the last data and do a linear fit, then you will get a first approximation of a linear function to be used as "baseline". Then extract the data in the middle. These could be a Gaussian like prophy technicians
