Parameters estimate statistics
WebFinally, when a parameter is being estimated by an estimator, it is designated by a “hat” on top: for example, if we have a sample statistic called a estimating a population parameter α[4], the estimated α will be , pronounced “alpha-hat”. By analogy, if a statistic b estimates a parameter β[5], the estimated β will be , pronounced “beta-hat”. WebIn a linear regression model with intercept, R square is defined as. where SSE is the residual (error) sum of squares and SST is the total sum of squares corrected for the mean. The adjusted R-square statistic is an alternative to R square that takes into account the number of parameters in the model.
