How to calculate fitted values
WebTo fit a model using INLA we need to take two steps. First, we write the linear predictor of the model as a formula object in R. Then, we run the model calling the inla() function where we specify the formula, the family, the data and other options. The execution of inla() returns an object that contains the information of the fitted model including several summaries … WebA fitted value is a statistical model’s prediction of the mean response value when you input the values of the predictors, factor levels, or components into the model. Suppose you …

WebFit Polynomial to Trigonometric Function. Generate 10 points equally spaced along a sine curve in the interval [0,4*pi]. x = linspace (0,4*pi,10); y = sin (x); Use polyfit to fit a 7th-degree polynomial to the points. p = polyfit (x,y,7); Evaluate the polynomial on a finer grid and plot the results.
