What is imputation definition?

Imputation is the process of replacing missing or incomplete data values with estimates. This is typically done when analyzing datasets, as missing data can skew the results and may prevent accurate conclusions from being drawn. Imputation methods vary, and can range from simple statistical techniques, such as mean imputation, to more complex algorithms that take into account multiple variables and patterns within the data. It is important to note that imputed values are not always perfectly accurate, and the results of imputation should be interpreted with caution.
