missing at random

How is MAR Different from Other Missing Data Mechanisms?

Missing data can generally be categorized into three types:
1. Missing Completely at Random (MCAR): The missingness is entirely unrelated to any data, observed or missing.
2. Missing at Random (MAR): The missingness is related to the observed data but not the missing data.
3. Missing Not at Random (MNAR): The missingness is related to the missing data itself.
Understanding these distinctions helps in choosing the right methods for data imputation and analysis.
