In statistics, M-estimators are a broad class of extremum estimators for which the objective function is a sample average. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. Both non-linear least squares and maximum likelihood estimation are special cases of M-estimators. It is the distinction between the way of combining our data, the estimator, and the result of the combination, the estimate. a function, called an estimator, that associates an estimate to each sample that could possibly be observed.

The functionality allows for manipulation of mathematical variables and symbols with just a few clicks. Calculator for determining whether a function is an even function and an odd function. An "estimator" or "point estimate" is a statistic (that is, a function of the data) that is used to infer the value of an unknown parameter in a statistical model.The parameter being estimated is sometimes called the estimand.It can be either finite-dimensional (in parametric and semi-parametric models), or infinite-dimensional (semi-parametric and non-parametric models). It uses sample data when calculating a single statistic that will be the best estimate of the unknown parameter of the population. Before being observed, the sample is regarded as a random variable.
