2015-02-26 Thread Mikael Olai Milhøj
Hi all I have been searching on the web in vain. I want to include a dummy variable in my ARIMA model. Let's say that I want to make an AR(1) model for X including a dummy variable which should be 1 for observation 4,5,6 and zero otherwise (let's say that there is 50 observations in total). How do

Hi, I'm having trouble trying to plot the density of the residuals against the standard normal distribution N(0,1). (I'm trying to see if my residuals are well-behaved). I know hwo to calculate the standardized residuals (I guess that there may be a simple way using a R function) and then plot th

Hi I have the unfortune to have some data saved as oxmetrics/pcgive file format (.in7 & .bn7). Is there any way to import data from this format into R? I have tried both google and the importing/exporting guide without any luck. Thanks in advance Best regards, /Mikael [[alternative HTM
