F-WUAB when being constructed in 1972. The aircraft was assembled at Airbus's Aérospatiale facility based in Toulouse, Occitania, France as the first Airbus A300 aircraft ever built, the prototype aircraft took its first flight on October 28th, 1972.
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.
It was the launch of the A320 in 1987 that guaranteed the status of Airbus as a major player in the aircraft market [26] – the aircraft had over 400 orders before it first flew, compared to 15 for the A300 in 1972. Airbus A320, the first model in the A318, A319, A320 and A321 family, introduced in 1988
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
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 notation () indicates an autoregressive model of order p.The AR(p) model is defined as = = + where , …, are the parameters of the model, and is white noise. [1] [2] This can be equivalently written using the backshift operator B as
Standardized coefficients shown as a function of proportion of shrinkage. In statistics, least-angle regression (LARS) is an algorithm for fitting linear regression models to high-dimensional data, developed by Bradley Efron, Trevor Hastie, Iain Johnstone and Robert Tibshirani.
The model is usually denoted ARMA(p, q), where p is the order of AR and q is the order of MA. The general ARMA model was described in the 1951 thesis of Peter Whittle , Hypothesis testing in time series analysis , and it was popularized in the 1970 book by George E. P. Box and Gwilym Jenkins .
