Weblm is used to fit linear models. It can be used to carry out regression, single stratum analysis of variance and analysis of covariance (although aov may provide a more convenient … Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related topic is regression analysis, which focuses more on questions of statistical inference such as how much uncertainty is present in a curve tha…

Simply select the function and click a button to download the FDF file and add the function to Origin, then find and use it when perform fitting. WebFeb 22, 2011 · Least squares is a special form of a technique called maximum likelihood which is one the most valuable techniques used for fitting statistical distributions. The technique involves maximising the likelihood function of the data set, given a distributional assumption. It is highly efficient and iterative solvers converge very rapidly.
