The least squares method is one of the methods for finding such a function. The least squares method is the optimization method. As a result we get function that the sum of squares of deviations from the measured data is the smallest. Mathematically, we can write it as follows: ∑ i = 1 n [ y i − f ( x i)] 2 = m i n.

February 16, 2021 by Zach Logarithmic Regression in Excel (Step-by-Step) Logarithmic regression is a type of regression used to model situations where growth or decay accelerates rapidly at first and then slows over time. For example, the following plot demonstrates an example of logarithmic decay:Degree 1: y = a0 + a1x. As we've already mentioned, this is simple linear regression, where we try to fit a straight line to the data points. Degree 2: y = a0 + a1x + a2x2. Here we've got a quadratic regression, also known as second-order polynomial regression, where we fit parabolas. Degree 3: y = a0 + a1x + a2x2 + a3x3..
