NettetWe begin by describing standard functional linear regression methodology, as discussed by, for example, Ramsay and Silverman ([24], Chapter 10). It is founded on spectral expansions of both the covariance of Xand its estimator and is constructed as follows. Let (X,Y,ε) denotea generic (Xi,Yi,εi) andput K(u,v)=cov{X(u),X(v)}, X¯ =n−1 P i … Simple linear regression is a parametric test, meaning that it makes certain assumptions about the data. These assumptions are: 1. Homogeneity of variance (homoscedasticity): the size of the error in our prediction doesn’t change significantly across the values of the independent variable. 2. Independence of … Se mer To view the results of the model, you can use the summary()function in R: This function takes the most important parameters from the linear model and puts them into a table, which … Se mer No!
