وجدت صعوبة شديدة لدخول المنتدى خلال الفترة الأخيرة وجئت اليوم متسللة خوفًا من ألا اتمكن من الدخول اليوم أيضًا، خاصة مع مواجهتي لمصطلح أحتاج إلى ترجمة له وهو :


Trimmed Mean CPI



في ويكيبيديا جاء ما يلي:


There are also other types of measuring inflation rates. In the United States the Dallas Federal Reserve computes a trimmed mean PCE price index, which separates "noise" and "signal". This is trimmed at 19.4% at the lower tail end and 25.4% at the upper tail. The Cleveland Federal Reserve computes a Median CPI and a 16% trimmed mean CPI. Trimmed means that the highest rises and declines in prices are trimmed by a certain percentage, attributing to a more accurate measurement on core inflation. In relation to this, the Median CPI is usually higher than the trimmed figures for both PCE and CPI. There also is a median PCE, but is not used for any purpose in determining inflation.

هل يمكنكم مساعدتي في التوصل لترجمة هذا المصطلح
