O que (quem) é material variance account - definição
Direct material variance
Direct material total variance
In variance analysis (accounting) direct material total variance is the difference between the actual cost of actual number of units produced and its budgeted cost in terms of material. Direct material total variance can be divided into two components:
Bias–variance tradeoff
PROPERTY OF A SET OF PREDICTIVE MODELS WHEREBY MODELS WITH A LOWER BIAS IN PARAMETER ESTIMATION HAVE A HIGHER VARIANCE OF THE PARAMETER ESTIMATES ACROSS SAMPLES, AND VICE VERSA
Bias variance; Bias-variance tradeoff; Bias-variance dilemma; Bias–variance dilemma; Bias-variance decomposition; Bias–variance decomposition; Bias and variance tradeoff; Bias--variance tradeoff
In statistics and machine learning, the bias–variance tradeoff is the property of a model that the variance of the parameter estimated across samples can be reduced by increasing the bias in the estimated parameters.
Allan variance
MEASURE OF FREQUENCY STABILITY IN CLOCKS AND OSCILLATORS
Allen variance; Allan deviation; Allan Variance; ADEV
The Allan variance (AVAR), also known as two-sample variance, is a measure of frequency stability in clocks, oscillators and amplifiers. It is named after David W.
