Estimator consistency refers to the property of an estimator to converge in probability to the true parameter value as the sample size increases. It is a fundamental criterion for evaluating the performance of an estimator in statistical inference, ensuring that with enough data, the estimator will yield accurate results.

The true parameter value is the actual value of a parameter in the population or process being studied, often unknown and estimated through statistical methods. Understanding and accurately estimating the true parameter value is crucial for making valid inferences and predictions about the population or process.

Sample size is a critical component in statistical analysis that determines the reliability and validity of the results. A larger sample size generally leads to more accurate and generalizable findings, but it must be balanced with resource constraints and diminishing returns in precision.

Statistical inference is the process of drawing conclusions about a population's characteristics based on a sample of data, using methods that account for randomness and uncertainty. It involves estimating population parameters, testing hypotheses, and making predictions, all while quantifying the reliability of these conclusions through probability models.
