Writing up a literature review.

Current progress.
I've spent a week working on the literature review. I finished the introductory part and skimmed through couple of classical time-series analysis books refreshing my knowledge of the well established methods of the time-series analysis and forecasting such as autoregressive ARMA/ARIMA models and based on these forecasting, lag analysis and spectrum analysis of the time series.

I think that while all these classical time-series analysis could be potentially used in the trajectory application for finding similarity between time series, it seems to be that this direction would require far more computations to be done (decomposing the time series) and would require a whole bunch of preliminary theoretical work researching specific models suitable for the software development and proving them, which seems to be really unnecessary and moreover impossible.

Interesting that while reading books and walking through the given practical examples from econometrics, I found that interrupted time series and lag analysis could an useful addition to the Hackystat analyzes family. Specifically it would be valuable to implement some kind of such analysis modules to see whether or not some development or managerial events (like (i) stopping regular development activity and switching to test coverage boosting; or (ii) adding/removing a developer to the team; (iii) switching development approach to TDD etc) really impact the development trends and how.

Plans.
This week I will be reviewing the time-series similarity measures and all kinds of applications based on this approach.

It is in my plans to start research on the time-series database indexing after the similarity measurement.

I hope that once these three parts will be done I will cover pretty much all of the stuff that I need to finish the literature review and sketch my path with dissertation proposal. Can't wait to get to this point.

Note on the development
While writing up the review I've started the design of the time-series analysis sub-module, DTW sub-module and thinking on the database (sensorbase) extension for the indexing.
