Cross-section of A300 F-OCAZ preserved at the Deutsches Museum. The aircraft was retired on August 27th, 1974, after only two years of service as a testbed by Airbus Industries and the aircraft was partially scrapped, but some parts were salvaged and placed on display at the Deutsches Museum based in Munich, Bavaria, Germany.
The Airbus A300 is a wide-body medium-to-long range airliner; it has the distinction of being the first twin-engine wide-body aircraft in the world. [8] [9]: 34 [12]: 57, 60 [19] In 1977, the A300 became the first Extended Range Twin Operations (ETOPS)-compliant aircraft, due to its high performance and safety standards.
In statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one [clarification needed] effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed dependent variable (values ...
A model with exactly one explanatory variable is a simple linear regression; a model with two or more explanatory variables is a multiple linear regression. [1] This term is distinct from multivariate linear regression , which predicts multiple correlated dependent variables rather than a single dependent variable.

The following is a list of orders, deliveries and backlog for the Airbus A330 by model as of 31 December 2024: Ord — number of aircraft ordered from Airbus by the specified customer; Del — number of aircraft delivered by Airbus to the specified customer; Bl — number of aircraft still to be delivered to the specified customer
Deming regression (total least squares) also finds a line that fits a set of two-dimensional sample points, but (unlike ordinary least squares, least absolute deviations, and median slope regression) it is not really an instance of simple linear regression, because it does not separate the coordinates into one dependent and one independent ...
For example, detailed notes on the meaning of linear time trends in the regression model are given in Cameron (2005); [1] Granger, Engle, and many other econometricians have written on stationarity, unit root testing, co-integration, and related issues (a summary of some of the works in this area can be found in an information paper [2] by the ...
