Dm Missing Values in Data Mining
Missing values occur when data is unavailable, lost during collection, or intentionally omitted. Handling them properly is crucial for model accuracy.
Strategies include deletion (removes rows/columns), imputation (fills with mean/median/mode/forward fill), and using algorithms that handle missing values inherently.
The choice of strategy depends on the percentage of missing data, the data type, and the mechanism of missingness (random vs systematic).
