Panel Data Treatment

Stata Panel Data Functions
  1. xtreg ..., re/fe
  2. xtabond (does not allow time-invariant variables)
  3. xthtaylor ... end(...) varying(...) no constant
Othe issues
  • Unbalanced Panel: make it balanced by Zeroing out/Compression.
  • Dynamic Panel: serial correlation.
  • Random vs. Fixed: Hausmen Test Significant P-value indicating the use of Fixed Effect.
  • Independent Variables: Endogenous vs. Exogenous, Time Variant vs. Time Invariant

Correlation Test Statitics in STATA

  • To generate p-value, use "pwcorr 1 2 3 ... sig star/print(.05)". Null Hypothesis H0: Rho = 0 Variables 1 and 2 are not related. Alternative Ha: Rho not equal to 0

  • Don't be defensive; stop fighting back for everything the interview said which you do not agree with.
  • Talk like you are smart. "I do not know this, but based on basic concepts. This should be..." When the interviewer asks something you are not familiar with, you should try to analyze the question based on relevant courses, projects and other experiences. The answer should be developed from general and larger concepts. Details are listed in a logic way. Finally, the results must be doable, simple, and reasonable (not theoretical).
