| ## Data Preparation & Missing Data Handling |
|
|
| The raw data was processed using a Python script to transform it into a clean, structured format. The key steps were: |
|
|
| 1. **Filtering**: The data was filtered to include only records for 'Namibia'. |
| 2. **Reshaping**: The original wide-format data (years as columns) was melted into a long format. |
| 3. **Merging**: Data from all indicator files was merged into a single DataFrame on 'Year'. |
| 4. **Handling Missing Data**: Missing values (`NaN`) were filled using a two-step strategy: linear interpolation followed by a back-fill to handle any remaining gaps at the start of the series. |
