Is “Inverse Hyperbolic Sine” the new “Ln”?

November 15, 2011

If you don’t already have Chris Blattman in your reading feeds, might i suggest the add? So, can we replace ln(x) with log(yi+(yi2+1)1/2)? Frances Woolley says so. i’m not an economist, so the “auto-reject” from AER isn’t an outcome i’m all that concerned about (see CB’s post here). That said, i do find the solution to computing a log-transformation on variables with high likelihood of zero-values an intriguing one. Perhaps, i should have borrowed CB’s preface of “If you know what ln(1+income) is, and why it’s a headache, you should read this post.”
