West Texas Intermediate (WTI), also known as Texas light sweet, is a grade of crude oil used as a benchmark in oil pricing.
A Software package developed by US Census bureau for seasonal adjustment in 1965. The X11 is non-model based, and uses filters to seasonally adjust data and estimate the components of a time series.
A software package originally developed by Statistics Canada in 1980 and updated in 1988 to X11ARIMA88, uses Box Jenkins AutoRegressive Integrated Moving Average (ARIMA) models to extend a time series. Essentially, the use of ARIMA modelling on the original series helps reduce revisions in the seasonally adjusted series so that the effect of the end-point problem is reduced.
X-12 or X-12-ARIMA is the U.S. Census Bureau's software package for seasonal adjustment.
A software package developed by the U.S. Census Bureau for seasonal adjustment. The X-12-ARIMA is the successor to X-11-ARIMA.
Combines the X-12-ARIMA package, developed at the US census bureau, with an implementation of the SEATS package for model-based seasonal adjustment, developed by Bank of Spain
X-12-ARIMA (Synonym to X12-ARIMA) was the U.S. Census Bureau's software package for seasonal adjustment.
