===Proxies for analysis===
The use of the model has been made by using the historical sales data of ''proxy'' products to forecast sales for OLED display mobile phones with an assumption that OLED display mobile phones would mimic the diffusion patterns of the proxies. Hence it was important to select the proxies carefully. We used the follwong following for this farecastforecast:
* iPhone - since this was the latest revolution in mobile phone devices and consumers would show a similar adoption behavior for a new mobile phone technology even though it comes at a price premium
* LCD/Plasma TVs & Monitors - consumers spent more money to purchase screens with superior quality by significantly increasing their budget
** LCD and Plasma TVs and LCD monitors were treated as a single analogous product(by ascribing different weights to these) for the forecast
