Theoretical estimate
Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured empirical data that has a random component. The parameters describe an underlying physical setting in such a way that their value affects the distribution of the measured data. An estimator … Visa mer For example, it is desired to estimate the proportion of a population of voters who will vote for a particular candidate. That proportion is the parameter sought; the estimate is based on a small random sample of voters. … Visa mer Unknown constant in additive white Gaussian noise Consider a received discrete signal, $${\displaystyle x[n]}$$, of $${\displaystyle N}$$ Visa mer Numerous fields require the use of estimation theory. Some of these fields include: • Interpretation … Visa mer • Media related to Estimation theory at Wikimedia Commons Visa mer For a given model, several statistical "ingredients" are needed so the estimator can be implemented.
