Noun1.geometric mean- the mean of n numbers expressed as the n-th root of their product statistics- a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population parameters ...
Assume that has a normal distribution with mean 0, variance and for all . Let be the least squares estimator of in model (8). A confidence ellipsoid of is then given as see, e.g., [54]. We note that, the volume of is proportional to . Thus D-optimality, which seeks maximizing ,...

Let Ψ and Σ be bounded sets of positive kernel operators on a Banach function space L . We prove several refinements of the known inequalities for the generalized spectral radius ρ and the joint spectral radius , where denotes the Hadamard (Schur) geometric mean of the sets Ψ and Σ. ...
Multiply the result by 100%, and your portfolio returned a geometric mean of 3.99% over five years, slightly less than the arithmetic mean of (5+3+6+2+4) ÷ 5 = 4. Calculate the Geometric Mean in a Spreadsheet Using a spreadsheet, you'll get a slightly different result. Use theGeome...
To find the geometric mean of two numbers, you multiply them and determine their square root. You can also raise the result to the power of the inverse of the number of values—for example, if there are four values, the inverse of the number of values is 1/4 or 0.25. How Is Geomet...
