Spatial weight matrices comparison.
| Spatial weight matrix | Pro | Con | Interpretation/Contribution |
|---|---|---|---|
| Method 1 - Distance | Simple to construct and understand Used often in literature | Less realistic | Convenient to use and easy to understand and interpret. Not realistic enough for real insight |
| Inadequate for clustering | |||
| Lacks temporal element | |||
| Method 2 - Mobile network | High spatial resolution Large amounts generated passively by mobile device users | Computationally expensive | Captures strong spatial associations over relatively short distances. Allows for the identification of patterns potentially missed by other methods |
| Difficult to obtain | |||
| Not representative | |||
| Privacy concerns | |||
| Method 3 - Weighted Facebook data | Freely available data Potentially more representative | Low spatial resolution | Captures association between focal points of human activity regardless of distance |
| Lacks specificity | |||
| Method 4 - Scaled Facebook data | Simple to construct and understand. Freely available data Potentially more representative | Lacks temporal elements | Adds additional information to previously simplistic model. Additional information improves clustering |
| Low spatial resolution |
