In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. Informally, it measures how far a set of numbers is spread out from their average value. Variance has a central role in statistics, where some ideas that use it include descriptive statistics, statistical inference, hypothesis testing, goodness of fit, and Monte Carlo sampling. Variance is an important tool in the sciences, where statistical analysis of data is common. The variance is the square of the standard deviation, the second central moment of a distribution, and the covariance of the random variable with itself, and it is often represented by , , or .
Var is a department in the Provence-Alpes-Côte d'Azur region of Southeastern France. It takes its name from the river Var, which flowed along its eastern boundary, until the boundary was moved in 1860. The Var department is bordered on the east by the department of Alpes-Maritimes, to the west by Bouches-du-Rhône, to the north of the river Verdon by the department of Alpes-de-Haute-Provence and to the south by the Mediterranean Sea.

Firs (Abies) are a genus of 48–56 species of evergreen coniferous trees in the family Pinaceae. They are found through much of North and Central America, Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus Cedrus (cedar). Douglas firs are not true firs, being of the genus Pseudotsuga.
Vector autoregression (VAR) is a statistical model used to capture the relationship between multiple quantities as they change over time. VAR is a type of stochastic process model. VAR models generalize the single-variable (univariate) autoregressive model by allowing for multivariate time series. VAR models are often used in economics and the natural sciences.
"The genus Banksia L.f. (Proteaceae)" is a 1981 monograph by Alex George on the taxonomy of the plant genus Banksia. Published by the Western Australian Herbarium as Nuytsia3(3), it presented George's taxonomic arrangement of Banksia, the first major taxonomic revision of the genus since George Bentham published his arrangement in Flora Australiensis in 1870.
Alex George's taxonomic arrangement of Banksia was the first modern-day arrangement for that genus. First published in 1981 in the classic monograph The genus Banksia L.f. (Proteaceae), it superseded the arrangement of George Bentham, which had stood for over a hundred years. It was overturned in 1996 by Kevin Thiele and Pauline Ladiges, but restored by George in 1999. A recent publication by Austin Mast and Kevin Thiele suggests that it will soon be overturned again.
Alex George's taxonomic arrangement of Dryandra was the first modern-day arrangement of that taxon. First published in Nuytsia in 1996, it superseded the arrangement of George Bentham, which had stood for over a hundred years; it would later form the basis for George's 1999 treatment of Dryandra for the Flora of Australia. In accordance with contemporary thinking, George treated Dryandra as a genus, dividing it into three subgenera, the largest of which was divided into 24 series. The arrangement stood until 2007, when Dryandra was transferred into Banksia as B. ser. Dryandra. No alternative has yet been proposed.
Dryandra subg. Dryandra is an obsolete clade of plant. It was a series within the former genus Dryandra. The name was first published at sectional rank as Dryandra verae in 1830, before being renamed Eudryandra in 1847, the replaced by the autonym at subgenus rank in 1996. It was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk Dryandra into Banksia.
