This is a specific R package for the estimation of Spatial Seemingly Unrelated Regression models by maximum likelihood or instrumental variable procedures. Moreover, 'spsur' implements a collection of Lagrange Multipliers and Likelihood Ratios to test for misspecifications in SUR models.
This is the first version of 'spsur'. We want to improve it in the future, therefore, any suggestions or comments related to the package would be very welcome. Your expertise and your feedback would be very important for us.
We hope you find this package interesting for your research and empirical work.
