Web2. Principal component analysis performs high-dimensional rotation of the source data to maximize its variance. The singular vectors represent the basis of the rotated coordinate system and the principal components are the source data projected onto this basis. The singular values represent the variances of the principal components. WebJul 29, 2015 · This can be done with the predict method which by default returns the differenced endogenous variable not the endogenous variable itself. To change this behavior, we must specify typ='levels': preds = fit.predict (1, 30, typ='levels') Then our predictions do have the same levels of our training data: tachycardia related cardiomyopathy
