enter image description herehere]2 I tried to convert my data to panel data but i kept experiencing an error message. The data is in the form of likert scale. The error message was
duplicate couples (id-time) in resulting pdata.frame to find out which, use, e.g., table(index(your_pdataframe), useNA = "ifany")
Also, i would like to conduct a probit and logit model with my data.
My data frame does not include duplicates but R Studio is assuming that they are duplicates. I do not want to remove any of my data. Can someone advise me on how to resolve the issue?. Or is there any way that i can make all my values unique without removing any of them?
Here are the functions that i used before trying to convert my data to panel data;
library(readxl)
sample <- read_excel("Documents/sample.xlsx")
View(sample)
pdata.frame(sample)
