I have 3 time series of returns and I want to predict one with the other. When I scatterplot them 1vs1 I can see they have a "cross"shape" as follow:

1 vs 2 2 vs 3

This happens at all time (if I scatterplot only the first data or the middle data or the end data). It seems there are 2 regression lines overlapping.

Would you have ideas for how to predict y axis with x axis ? Thanks

    This looks like more of a statistics question than an open data question. – csk Jun 16 at 19:21
