Sample Bias Coefficient

An estimate of expected error in the sample mean of variable $A$ , sampled at $N$ locations in a parameter space $x$ , can be expressed in terms of sample bias coefficient $\rho$ -- defined as the average auto-correlation coefficient over all sample point pairs. This generalized error in the mean is the square root of the sample variance (treated as a population) times $\frac{1+(N-1)\rho}{(N-1)(1-\rho)}$ . The $\rho = 0$ line is the more familiar standard error in the mean for samples that are uncorrelated.
