So I am a beginner to R but I am running some code which simulates 100 observations of a y variable that follows the formula y_t=1+.5*y(t-1)+u. I then want to run a regression of y on y(t-1) and y_(t-2) and a constant. When I run the regression using the dyn package it shows the coefficient on y_(t-2) as NA. Anyone have any thoughts on this? Now, for lots of other regression things, there are very convenient ways to express them in the formula, such as poly(x,2) and so on, and these work directly using the unmodified training and test data. So, I'm wondering if there is some way of expressing lagged variables in the formula, so that predict can be used? Ideally: 9 Dynamic regression models.

In most situations, one of the best predictors of what happens at time t is what happened at time t -1. x = alag (x1) + blag (x2) + clag (x3) + dlag (y1) + elag (y2) + flag (y3) + glag (z1) + hlag (z2) + ilag (z3) -- eq 2. Intuitively, I think that the combination of the three factors together for a particular day is useful for the prediction. For example, I was wondering why some researchers use lagged values to normalize their regression variables? I read a couple of research papers (economics/finance) and often I see that they normalize their 2017-06-26 * In economics the dependence of a variable Y (dependent variable) on another variables(s) X (explanatory variable) is rarely instantaneous. Vary often, Y responds to X with a lapse of time.

* A lagged variab Try the ARIMA function. The AR parameter is for auto-regressive, which means lagged y. xreg = allows you to add other X variables.

We have some current data, and we make the regression model (could be any machine learning or statistical model, I just used regression for simplicity). We can also include lagged variables in multiple regression models. Lagged values are used to capture the ongoing effects of a given variable. The lag period is based on managerial insight and data availability.
