The process for finding a curve that fits multiple curves represented as individual data points in a dataset is called curve fitting. The steps involved in this process are as follows:
Collect the data: Collect the data representing the individual curves that need to be fitted with a single curve.
Choose the type of curve: Choose the type of curve that best fits the data. This could be a polynomial, exponential, logarithmic or any other type of curve.
Determine the parameters: Determine the parameters of the chosen curve. This involves adjusting the coefficients or constants in the equation for the curve to best fit the data.
Perform curve fitting: Perform curve fitting on the dataset using a software package like MATLAB, Python or R. This involves using the least squares method to minimize the difference between the actual data points and the fitted curve.
Analyze the fit: Analyze the fit of the curve using statistical measures like the R-squared value, root mean square error (RMSE), mean absolute error (MAE), etc. A good fit would have a high R-squared value and low errors.
Refine the fit: If the fit is not good enough, refine the fit by adjusting the parameters or using a different type of curve.
Evaluate the results: Evaluate the results and draw conclusions from the fitted curve.
