No Variation in Treatment Status error

[MattJames242]

Hi,

I have formatted my dataset so that it is in the same form as the california_99 dataset, and applied a 1 in the treated column for treated units and a 0 for all other units. However when I run 'setup = panel.matrices(GoodsExports)' it produces an error "Error in panel.matrices(GoodsExports) : There is no variation in treatment status", I was wondering how I can remedy this?

Try this:
setup = panel.matrices(as.data.frame(GoodsExports))
