Possibly of limited use to the original poster, but of interest more generally, there are a number of tools developed in the 70s for updating the matrix decompositions. There's at least one in my 1979 book "Compact numerical methods for computers" (still in print apparently) -- we didn't have en

I used rpanel() to do an interactive regression of a time series. My use was not as involved as yours, but it might give you an idea of how to approach. Here's a http://chartsgraphs.wordpress.com/2009/05/08/rpanel-package-adds-interactive-capabilites-to-r/ link to my blog post. -- View this m

Thank you all for the help, and as a side note I'm not a student, so this isn't a homework assignement, I'm just new to R. -- View this message in context: http://n4.nabble.com/iterative-regressions-adding-a-new-line-of-data-each-time-tp1457725p1459260.html Sent from the R help mailing list arc

Hi, I am pretty new to R. I'm trying run a regression repeatedly, adding a new data point each time, and then storing the predicted Y values. For example, let's say I have 500 data points and I run the regression. I would then like to store the Y value, run the regression again using 501 data poin
