A Unified Weight Formula for Calculating the Sample Variance from Weighted Successive Differences
The basic formula to calculate sample variance is based on the sum of squared differences from mean. From computational perspective, mean calculation is nondesired as it can introduce computing errors. Previous researches have proposed to use weighted formula of the successive differences to calcula...
