How to Perform Logarithmic Regression by Hand?

[Phox]

I'm trying to write some code to do a regression on data weight (x) and time (y). As best as I can tell, the model should be y = b1 + b2ln(x), but I don't know how you can do this by hand (I know how to in R...). I also know how to do a simple linear regression by hand.

Can it be done using the least squares method?

Well, this is a linear equation in x'=ln(x). So you could do a linear regression of y vs x'.
