I may be totally off base with this, but I'm wondering what exactly this would suggest or why you want to do it. Specifically "multiple regression with only intercept" -- how is it multiple if you don't have any regressors? Furthermore, you want to run a "regression" on a single data point -- really?
Best I can figure, an "intercept-only" regression is basically just the mean of the data (if you have no variates, your best estimate as to the mean of what you'll see is, well, just the mean [plus or minus some stuff about the median we'll ignore here]....) If I'm right about this, use of the lm() function is far more powerful than you actually need and a simple cumulative rolling mean, in conjunction with the rev() function, will suffice. Maybe you could say more about this odd request and we could provide a little more guidance, Michael Weylandt On Mon, Sep 12, 2011 at 10:20 AM, Trying To learn again < tryingtolearnag...@gmail.com> wrote: > Hi all, > > I have a time series a column vector with the ordered data so that the > first > column is the first observation and so on. > > The fact is that I want to run a multiple regression with only intercept. > > My first task is to run the regression on the first observation (1 from > 276) > and at the same time the same type of regressión on the 275 data. > > Then, is to run a regression on 2 of the data (the first and the second > observation) and other with the 274 rest of observations.... > > ... > > The final tram of the loop would the to run 1 regression with the 275 first > observations and one with the last observation. > > I want to save each pair of regression made in each loop. > > I have seen that the regression I want is > > data1 > > But how Shoud I use mapply or sapply?
