Nettetthe existing R package nonlinearTseries just conducts general nonlinearity tests. In addition, NTS utilizes the out-of-sample forecasting to evaluate different TAR models to avoid overﬁtting, while other R packages such as tsDyn just compare TAR models based on AIC and residuals. (3) NTS offers NettetIn this blog post, we are going through the underlying assumptions of a multiple linear regression model. These assumptions are: Constant Variance (Assumption of Homoscedasticity); Residuals are normally distributed; No multicollinearity between predictors (or only very little); Linear relationship between the response variable and …

NettetSteven - This is a really good question. The power equation you cited, P = v^2/R is not linear. It does not pass the two tests for linearity (scaling and additivity). The plot of power vs voltage is not a straight line through the origin. However, the i-v equations for R, L, and C do pass those tests. But you bring up a good point.
