The package is a panel adaptation of the gets package see here.
This code is being developed by Felix Pretis and Moritz Schwarz. The associated working paper is published under “Panel Break Detection: Detecting Unknown Treatment, Stability, Heterogeneity, and Outliers” by Pretis and Schwarz, which is available at SSRN here and was applied to a study by Nico Koch and colleagues on EU Road CO2 emissions, which was published in Nature Energy in 2022.
You can install the released version of getspanel from CRAN with:
And the development version from GitHub with:
library(getspanel)
data("EU_emissions_road")
# let's subset a few countries to make this faster
subset <- c("Austria", "Belgium", "Germany", "Denmark", "Spain",
"France", "Greece", "Ireland", "Italy", "Netherlands", "Sweden", "United Kingdom")
EU_emissions_road <- EU_emissions_road[EU_emissions_road$country %in% subset, ]
is1 <- isatpanel(data = EU_emissions_road,
formula = transport.emissions ~ lgdp + lpop,
index = c("country","year"),
effect = "twoways",
fesis = TRUE,
print.searchinfo = FALSE # to save space we suppress the status information in the estimation

Let’s explore the other plots that we can use:
We can plot the counterfactuals as well:
We can plot the residuals against an OLS model:
An example using coefficient step indicator saturation and impulse indicator saturation:

index = c("country","year"),
effect = "twoways",
