The third must have 10! Very No, It has only 8. Why do you think it shall have 10? > confusing because there is no 10th observation! You are right, there is no 10th and also no 9th observation. > > # Adjusted Real rate - P > > Sweden.p.adjust <- c(4.70243, 1.3776655, 1.117755, 1.6695175, 1.59282, > > 1.1017625, -0.04295, 2.2552875, 0.0552875) > > > > # Adjusted Inflation deviation > > Sweden.infl.dev.adjust <- c(0.110382497, -0.261612509, 0.040847515, > > -0.195062497, -0.234362485, -0.023408728, 0.206421261, -0.079401261, > > 0.071828752) > > > > # Adjusted GDP-gap > > Sweden.GDP.gap.adjust <- c(0.673792123, 1.196706756, 1.196131539, > > 0.646944002, -0.312886525, -1.180620213 -0.525964648, -0.369401194, > > -0.003280389) > > > > # OLS regression using ADJUSTED data.# > > Sweden.Taylor.real.adjust <- lm(Sweden.p.adjust ~ Sweden.infl.dev.adjust + > > Sweden.GDP.gap.adjust) > Error in model.frame.default(formula = Sweden.p.adjust ~ > Sweden.infl.dev.adjust + : > variable lengths differ (found for 'Sweden.GDP.gap.adjust') > > Why is this happening?
