Machine learning/Statistics Fundamentals

Point estimation is the process of calculating a statistic from a sample dataset.

  • A point estimator is any function for a sample.
  • Therefore, any statistic is a point estimator

Methods of finding point estimations

  • Method of Moments
  • Maximum Likelihood Estimators
  • Bayes Estimators
  • Maximum a posteriori estimator

Bayes EstimatorsEdit

Using the Bayesian rule
