path.plot {Synth} | R Documentation |
This function plots the trajectories of the outcome variable for the treated unit and the
synthetic control group constructed by synth
and dataprep
. The user can specifify whether the whole
time period or only the pretreatment period should be plotted.
path.plot(synth.res = NA,dataprep.res = NA,tr.intake = NA,Ylab = c("Y Axis"),Xlab = c("Time"),Ylim = NA,Legend=c("Treated","Synthetic"),Legend.position=c("topright"),Main = NA,Z.plot = FALSE)
synth.res |
Output list created by synth . |
dataprep.res |
Output list created by dataprep . |
tr.intake |
Optional scalar to indicate the time of treatment intake with a vertical line. |
Ylab |
Optional label for Y axis. |
Xlab |
Optional label for X axis. |
Ylim |
Optional Ylim. |
Main |
Optional main title. |
Legend |
Optional legend text (e.g. c("Treated","Synthetic")); see ?legend for details. |
Legend.position |
Optional legend position (e.g. "bottomright"); see ?legend for details. |
Z.plot |
Flag. If true, only pretreatment period is plotted. |
The trajectory of the outcome for the synthetic control group is calculated as: dataprep.res$Y0plot%*% synth.res$solution.w. You can use this calculation to construct custom made plots.
The plot of trajectories.
