Principal Components variance explained

[Brent Pedersen]

Hi, I'm using stat.PC and just verifying that I'm not missing a way to get the proportion of the total variance explained?

The way I can see is to take the sum of the the row-wise variances and then divide the pc.Vars() by that. 

thanks,

pov := pc.Vars(nil)
floats.Scale(1/floats.Sum(pov), pov)
