Transformation of a Uniform Distribution needed

[consuli]

Hello,

I have got a crazy distributed p4. (See file attachment).

How can I transform a uniform distribution into the one of p4? Probit Transformation?

Find estimate of cumulative distribution F and make draws from uniform u1,u2,... transforming them to p4 using quantile function F^-1(ui)

This does not appear to be a uniform distribution. Might you have a mixture of two or more distributions? If you have data collected in time sequence vs. a random sample, try plotting the data in time order to see if there are trends or shifts in the data.
