Webb23 aug. 2004 · Abstract Theoretical variance #1 (Theo1) has been developed at NIST to improve the estimation of long-term frequency stability. Its square-root (Theo1-dev) has two significant improvements over the Allan deviation XX called ¿Adev" in estimlating long-term frequency stability in that (1) it can evaluate frequency stability at averaging times …

Webb24 jan. 2024 · The variance, typically denoted as σ2, is simply the standard deviation squared. The formula to find the variance of a dataset is: σ2 = Σ (xi – μ)2 / N where μ is the population mean, xi is the ith element from the population, N is the population size, and Σ is just a fancy symbol that means “sum.”
