I cannot find the relationship between these two columns...other than I know that they both increase or decrease in value at the same time. I'm not a math person, but I would appreciate any help someone might be able to give.
\begin{array} {lll} &DATE &COL A &COL B\\ &12/22/2015\quad &65.9 &9.984\\ &12/21/2015 &61.58 &9.826\\ &12/18/2015 &54.76 &9.624\\ &12/17/2015 &45.53 &9.416\\ &12/16/2015 &41.81 &9.346\\ &12/15/2015 &41.18 &9.334\\ &12/14/2015 &41.25 &9.336\\ &12/11/2015 &42.66 &9.378\\ &12/10/2015 &40.12 &9.322\\ &12/9/2015 &36.77 &9.25\\ &12/8/2015 &32.17 &9.156\\ &12/7/2015 &27.93 &9.074\\ &12/4/2015 &27.1 &9.058\\ &12/3/2015 &27.14 &9.06\\ &12/2/2015 &27.75 &9.096\\ &12/1/2015 &26.9 &9.076\\ &11/30/2015 &25.16 &9.034\\ &11/27/2015 &22.05 &8.958\\ &11/25/2015 &19.26 &8.89\\ &11/24/2015 &14.85 &8.784\\ &11/23/2015 &14.28 &8.77\\ &11/20/2015 &14.36 &8.782\\ &11/19/2015 &14.37 &8.784\\ &11/18/2015 &13.36 &8.754\\ &11/17/2015 &13.47 &8.776\\ &11/16/2015 &14.34 &8.954\\ &11/13/2015 &15.69 &9.21\\ &11/12/2015 &17.4 &9.496\\ &11/11/2015 &20.15 &9.882\\ \end{array}
