Calcution Of Annealing Temperature Of Primers What Is Pearson 6 Distribution? In What Situation We Can Find This Statistical Distribution?

What is Pearson 6 distribution? In what situation we can find this statistical distribution? - calcution of annealing temperature of primers

I am an engineering student. I am looking for information on the distribution of Pearson 6, but found difficulty in obtaining detailed information from the Internet or reference pounds.
I am conducting a simulation in the mail system and work against the proliferation of Pearson 6 battle suggests that the time of the server service will be represented. I want to prove that this model is right for me or for a better balance to be found.
This distribution is, in fact, suggested by a statistical software, but simply do not trust him. How do I get a good distribution (Calcute Guide) for a dataset of more than 10,000 data?
