I have the following database: I know that the data points are not sufficient to producec an output but here is the scenario I have: 


id date x_1 x_2 x_3 1 1/1/2001 1 0 0 1 1/2/2001 1 0 0 1 2/2/2001 0 1 0 1 3/2/2001 1 1 0 2 1/1/2001 1 0 0 2 1/2/2001 1 0 0 2 2/2/2001 0 1 0 2 3/2/2001 1 1 0 1 1/1/2002 1 0 1 1 1/2/2002 1 1 0 1 2/2/2002 1 1 0 1 3/2/2002 1 1 0 1 7/1/2002 1 0 1 1 11/2/2002 1 1 0 1 32/2002 1 1 0 1 3/2/2002 1 1 0

I have two periods 1/2001-12/2001 and 1/2002-12-2002. I am trying to compare the slopes of each period for each of the x. So I am assuming I will build a speperate model for x1, x2, x3. Each id could have multiple entries per month but my goal is to compare the cumulative change across al ids in the first period compared to the second period. Any help is appreciated

It is more like time series's PANEL data. Could you post it at Time Series Analysis forum? Someone could you some advice .

What is ANOVA?

ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
