Error in synth.core (object 'r.cv' not found)

[munshimdrasel]

Hy,

I'm getting the following error while running gsynth package.

Error in synth.core(Y = Y, X = X, D = D, I = I, W = W, r = r, r.end = r.end, : object 'r.cv' not found In addition: Warning messages: 1: In min(T0) : no non-missing arguments to min; returning Inf 2: In min(T0.ub) : no non-missing arguments to min; returning Inf 3: In min(T0.ub) : no non-missing arguments to min; returning Inf 4: In min(T0) : no non-missing arguments to min; returning Inf 5: In matrix(est.co$xi, TT, Ntr, byrow = FALSE) : data length exceeds size of matrix

I'm using following datasets (showing first 6 lines):

      ID NOx..tons. HEAT.INPUT SUM_OP_TIME   time inputed

out <- gsynth(NOx..tons. ~ inputed+ HEAT.INPUT + SUM_OP_TIME, data=ampd_sy_va3, index = c("ID","time"), force = "two-way", CV = TRUE, r = c(0, 5), se = TRUE, inference = "parametric", nboots = 1000, parallel = FALSE)

Can you please let me know how to resolve this?

Hi are you using the most up-to-date version from Github? If yes, could you check your data by plotting using the panelView package?

Hello Professor,

I'm using the version from Github. After looking into my data using panelView I'm seeing there are missing data in my datasets.

In such case what should I do? Do I need to remove missing data?

Regards, Rasel

Perhaps the problem may be that for post-treatment periods, you only have observations for treated units (which cannot be used for fitting the model)?
