What is the benefit of OU vs regression for modeling data, say data in the form of ($x,y$) pairs?

What kind of technique is to be adopted if I have to find an equation or model for say, $D$ depends on $C$, $C$ changes for a set of $B$, which changes for different $A$.

From numerical simulation and regression analysis I discovered that the root-mean-square amplitude of white noise with bandwidth $\mathrm{\Delta }\phantom{\rule{negativethinmathspace}{0ex}}f$ is proportional to $\sqrt{\phantom{\rule{negativethinmathspace}{0ex}}\mathrm{\Delta }\phantom{\rule{negativethinmathspace}{0ex}}f}$. How can this be derived mathematically ?

Find a regression to this : $a\equiv t\phantom{\rule{0.444em}{0ex}}\left(\mathrm{mod}\phantom{\rule{0.333em}{0ex}}\mathrm{\Delta }\right)$, $a$ and $\mathrm{\Delta }$ are the unknowns constants.

Is it a "standard" Math/Numerical-Analysis hack to add a relatively small number e.g. 1*10E-5 to the diagonal of a squared matrix to ensure LU Decomposition (or whichever decomposition algorithm is applicable)? As opposed to "partially/totally pivoting"?
