Estimation is the process of making an educated guess or calculation about the value, quantity, or extent of something based on available information and knowledge.
Types of estimation include:
1. Point estimation: Involves estimating a single value for an unknown parameter, such as the mean or proportion of a population.
2. Interval estimation: Involves estimating a range within which a parameter is likely to fall, along with a level of confidence associated with this range.
3. Confidence intervals: Specific types of interval estimations that indicate the range in which a population parameter is likely to fall, along with the level of certainty associated with this range.
4. Estimation by analogy: Involves using a similar situation or data set to estimate values or outcomes in a different context.
5. Regression estimation: Involves using regression analysis to estimate the relationship between variables and make predictions based on this relationship.
6. Bayesian estimation: Involves using Bayesian statistics to update probabilities and make estimates based on prior knowledge and new information.
7. Extrapolation: Involves extending known data or trends into the future to make predictions or estimations about future values or outcomes.
8. Judgmental estimation: Involves relying on the expertise and judgment of individuals to make estimates based on their knowledge and experience.
9. Parametric estimation: Involves making estimates based on assumptions about the distribution of the data or population being studied.
