With ProbabilityDistribution you define a function, that Mathematica handles
as a arbitrary ProbabilityDistribution you can define.

Mathematica offers you the transformation from a PDF to a CDF (cumulative
distribution function). That is the part of the functional programming
concept of Mathematica.

What you search, I think, is bfitting the Parameters of a classic PDF
to the data you offer:

xv={-2.1, 3.45, 7};

Kind regards wishes Peter
