All the gory details inside. [more inside]

Stats filter. I am doing multivariate regression for the first time and I want to understand what I'm doing, having gone beyond my formal training. I have many possible ways I could formulate the regression (different variables to include) and I want to find a model that is both the best possible fit while using the fewest number of variables. How? [more inside]

In an OLS regression the coefficient is b = cov(X,Y)/var(X). What is the plain english interpretation of this coefficient in terms of variations (ie. b is the variation in Y that can be explained by variation in X)?
How does this relate to r^2?

I've spent the past day or so trying to figure out how to calculate a hidden value in my data. It varies linearly with time, or closely enough that we can make that assumption within any given dataset. Where this goes beyond a simple linear regression is that each datapoint is known to be above or below the hidden value. The data is collected in a C# program and processed in Excel; an Excel function would be the ideal solution. [more inside]
