Kumaraswamy distribution
dkumar = function(x,a,b) a*b*(x^(a-1))*((1-x^a)^(b-1)) pkumar = function(x,a,b) 1-(1-x^a)^b (I've based this entirely on the wikipedia entry on the Kumaraswamy distribution [http://en.wikipedia.org/wiki/Kumaraswamy_distribution], so best to check both my replication of the formula there and the accuracy of the wikipedia entry itself)
