An unbiased estimator is when a statistic does not overestimate or underestimate a population parameter. Tax liability is the total amount of tax debt owed to a government by an individual, corporation, or other entity. This applies even if A fitted linear regression model can be used to identify the relationship between a single predictor variable x j and the response variable y when all the other predictor variables in the model are "held fixed". In statistics, pooled variance (also known as combined variance, composite variance, or overall variance, and written ) is a method for estimating variance of several different populations when the mean of each population may be different, but one may assume that the variance of each population is the same.
