Spatial weights matrix with Stata: creation, visualization and validation The creation and the use of spatial weights matrices is an important step for the implementation of many spatial econometrics techniques. All the variables (Q3-Q22) are numeric on an ordinal scale (1-5). The majority of the data is either value 4 or 5. However, Stata takes a lot of time for the fitting target model iterations (that are all not concave, it says so) to tell me that convergence was not achieved. I'm using maximum likelihood with missing values as estimation method. This post shows how to create animated graphics that illustrate the spatial spillover effects generated by a spatial autoregressive (SAR) model.
