How to get equation

[SriRajesh]

Hi,

I have two curves: Golden curve and new curve. How to find the equation which minimizes the error between golden curve and new curve.

Golden        New curve
0.435180483	  0.606003359
0.904945471	  0.544934303
0.840420015	  0.391903693
0.440197587	  0.640708699
0.71810969	  0.428396977
0.117289368	  0.87376984
0.774790867	  0.596429227
0.422865885	  0.658253197
0.773947268	  0.545480876
0.823069033	  0.807833241
0.165066477	  0.2152713
0.959118286	  0.384702233
0.585423363	  0.754240037

I want to shift each point in new curve such as to minimize the error between golden curve and actual curve.
I did not try any code, as I did now how to approach this. Kindly some one help.
