The simplest case of a normal distribution is known as the standard normal distribution or unit normal distribution. This is a special case when μ = 0 {\textstyle \mu =0} and σ 2 = 1 {\textstyle \sigma ^{2}=1} , and it is described by this probability density function (or density): φ ( z ) = e − z 2 2 2 π . {\displaystyle \varphi (z ...
In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of ...

Vietnamese (tiếng Việt) is an Austroasiatic language spoken primarily in Vietnam where it is the official language. It belongs to the Vietic subgroup of the Austroasiatic language family. [6] Vietnamese is spoken natively by around 85 million people, [1] several times as many as the rest of the Austroasiatic family combined. [7]
The comparatively fatter tails of the leptokurtic densities are illustrated in the second image, which plots the natural logarithm of the Pearson type VII densities: the black curve is the logarithm of the standard normal density, which is a parabola. One can see that the normal density allocates little probability mass to the regions far from ...
Standard normal deviates arise in practical statistics in two ways. Given a model for a set of observed data, a set of manipulations of the data can result in a derived quantity which, assuming that the model is a true representation of reality, is a standard normal deviate (perhaps in an approximate sense).
VSCII (Vietnamese Standard Code for Information Interchange), also known as TCVN 5712, [2] ISO-IR-180, [3].VN, [4] ABC [4] or simply the TCVN encodings, [4] [5] is a set of three closely related Vietnamese national standard character encodings for using the Vietnamese language with computers, developed by the TCVN Technical Committee on Information Technology (TCVN/TC1) and first adopted in ...
IME scripts such as AVIM, Mudim, and VietTyping can be found on most Vietnamese message boards, the Vietnamese Wikipedia, and other text-intensive websites. The Vietnamese Web browser Cốc Cốc comes with an input method built-in. Input methods allow words to be composed in a more flexible order than keyboard layouts allow.
