For the last two weeks, I have been attempting to perform a switching regression analysis upon the data provided by Dr Poon. To this end, I have read various papers by Bezdek and Hathaway, Chau, as well as examples of switching regression. On Wednesday, I located an online tutorial which explained how to perform this analysis in R, and as such, I will attempt to do so over the weekend, and post the results up.
Additionally, fuzzy clustering is now being performed by data engine. The final results of this analysis will be posted up later. However, preliminary indications match that of Dr Poon's findings now, as compared to the ambiguous results derived from R.
