To help decide which values of $$\tau$$ to use in the QR analysis, I check the values at the quantiles of my data.

0.95 0.97 0.99 0.999
MPPC 0.021 0.035 0.070 0.167
CHiCAGO 1.610 2.533 5.270 15.875
PP 0.002 0.010 0.051 0.407

### 1. Big regression

I run a multiple quantile regression using all of the emission proportions for a subset of 1,00,000 rows of the activated cell data.

The bait emission proportions all seem to have a small negative effect on MPPC, although most of these are not significant (especially for 95% quantile regression). Note that this sort of makes sense because these baited regions were chosen as they were near a TSS so are likely to be open anyway, whereas the prey fragment can be from anywhere in the genome.

The prey emission proportions all have varying effects, suggesting that the inference should be collapsed over several emission states.
