Polynomial fitting matlab
WebHello, I have your for deuce independent variables and one dependent vary (obtained from experiment). I need to fit this data using linear regression to a 10 coefficient third-party stage polynomi... WebI'm using the fit and fitlm functions to fit various linear and polynomial regression models, and then using predict and predint to compute predictions of the response variable with lower/upper confidence intervals as in the example below. However, I also want to calculate standard deviations, y_sigma, of the predictions.Is there an easy way to do that?
