Could someone suggest a good and simply written book on econometric analysis for beginners? I am interested in time series data analysis and its forecasting methods. Thank You all in advance)
Wooldridge's introductory text (Introductory Econometrics: a modern approach) is possibly the best, but it might be not the best for time series. You can also have look at Kennedy's one (A guide to Econometrics).
"Econometric Models and Economic Forecasts" by Robert Pindyck and Daniel Rubinfeld has a good section on Timeseries. The most advance text is by Box and Jenkins on Time Series.
I would recommend Mostly Harmless Econometrics by Angrist and Pischke. If you’re looking for stata code too, impact evaluation in practice by the world bank has a lot of useful applied econometrics and code. Versions of both can be downloaded online.
Econometrics is a deeply complex subject. I do not think you are going to find a "simple" text that is both complete and thorough. So I will dispense with your request for "simple" and just give you suggestions that are complete and thorough. You most definitely want Econometric Analysis by William Greene. It is arguably the definitive text on Econometrics. It is the most thorough and complete econometrics text that I know. Econometric Models and Economic Forecasts by Pindyke and Rubenfeld is heavily time-series tilted and offers some good insights and examples. Those are the 2 texts which you must have on your shelf if you are a real econometrician. You will find that there is quite a bit of 'art' to econometric analysis. After doing hundreds of histograms of regressions, you will begin to 'feel' the types of serial correlation that are present in the patterns. Like I said, it is more art than science, so you will just need to experience it for yourself. The manuals for eViews, SAS, Stata, and R can give you some tips for interpreting those histograms, but largely it is a skill to recognize the patterns. I hope this helps.
