Making a sensible guess or a rough calculation is known as estimation. An estimate is not an exact calculation. You can use estimation when you do not need to know an exact number or you can use it to ...

For average eyes, IOL power estimation calculations are reasonably accurate because the assumptions that are made by the formulae all hold true: The anterior chamber is an average depth, the corneal ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 75, No. 10 (Oct., 1978), pp. 5094-5098 (5 pages) An approach is described for the estimation of the number of rare ...

Mixed model analyses via restricted maximum likelihood, fitting the so-called animal model, have become standard methodology for the estimation of genetic variances. Models involving multiple genetic ...
