# Manual computation of Gower's similarity coefficient

There is an example on the computation of Gower's similarity coefficient on the page,

Gower's similarity coefficient

I am trying to work out the similarity manually between patient 1 and 2, however my computation is giving me completely different results. Here is the formula I use, in the order of the variables and their types $$\frac{\left(1*\left(1 - \left(\frac{150-120}{150-110}\right)\right)+ 0 + 1 + 1 + 0\right)}{5}$$ I still cannot get the 0.0625 as indicated in the example. What am I doing wrong?

• Welcome to the site, @Nimonika. I took the liberty of adding $\LaTeX$ to your equation to make it easier to read. Please make sure it still says what you want. If not you could edit it or rollback. Jan 29 '13 at 23:09

This yields: $$\frac{(1-(\frac{150-120}{150-110})+0+0+0+0}{1+1+1+0+1} = 1/16$$
