# Extensive Definition

Estimation is the calculated approximation of a result
which is usable even if input data may
be incomplete, uncertain, or noisy.

In mathematics, approximation or
estimation typically means finding upper or lower
bounds of a quantity that cannot readily be computed precisely
and is also an educated guess . While initial results may be
unusably uncertain,
recursive input from
output, can purify
results to be approximately accurate, certain, complete and
noise-free.
