14. Predictive Accuracy of Linear Models with Ordinal Regressors
University essay from Uppsala universitet/Statistiska institutionenAbstract : This paper considers four approaches to ordinal predictors in linear regression to evaluate how these contrast with respect to predictive accuracy. The two most typical treatments, namely, dummy coding and classic linear regression on assigned level scores are compared with two improved methods; penalized smoothed coefficients and a generalized additive model with cubic splines.
