Hi everyone, i am preparing a panel dataset to run analysis for my research project. The data files come separately and i have to combine them into one. This i have done using "merge" command functionality in Stata version 14. (Please find my attached do file). The merged dataset looks ok,..yet my programming is hazy and i am sure there can be a better method and i need t perfect my do file. Any contributions will be most helpful. Find the command and the dataset
