This app provides a platform to import the data, visualize it and construct a curve or mathematical function, that has the best fit to the series of data points.
DESCRIPTION
Data fitting is the process of fitting models to data and analysing the accuracy of the fit. Engineers and scientists use data fitting techniques, including mathematical equations and nonparametric methods, to model acquired data.
This app fits the data in graphical form and also gives the fitting parameters that describe the mathematical relation between the given data variables and the quality of the fit.
Data fitting is the way we model or represent a data spread by assigning a 'best fit' function (curve) along with the entire range. Ideally, it will capture the trend in the data and allow us to make predictions of how the data series will behave in the future which includes:
(1) POLYNOMIAL
(2) EXPONENTIAL
(3) POWER
(4)FOURIER
(5)MULTIPLE LINEAR REGRESSION
And it also includes the nonparametric function "SMOOTHING" which smoothens the given data.
