Pandas (styled as pandas) is a software library written for the Python programming language for data manipulation and analysis. In particular, it offers data structures and operations for manipulating numerical tables and time series .
Figure 1. A simple bimodal distribution, in this case a mixture of two normal distributions with the same variance but different means. The figure shows the probability density function (p.d.f.), which is an equally-weighted average of the bell-shaped p.d.f.s of the two normal distributions.
The Lempel–Ziv–Markov chain algorithm (LZMA) is an algorithm used to perform lossless data compression.It has been used in the 7z format of the 7-Zip archiver since 2001. [1]
In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.The general form of its probability density function is [2] [3] = ().
Given two objects, A and B, each with n binary attributes, SMC is defined as: = = + + + +. where is the total number of attributes where A and B both have a value of 0,; is the total number of attributes where A and B both have a value of 1,
An entity–attribute–value model (EAV) is a data model optimized for the space-efficient storage of sparse—or ad-hoc—property or data values, intended for situations where runtime usage patterns are arbitrary, subject to user variation, or otherwise unforeseeable using a fixed design.
NumPy (pronounced / ˈ n ʌ m p aɪ / NUM-py) is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays. [3]
The ISO/IEC 8859 standard is designed for reliable information exchange, not typography; the standard omits symbols needed for high-quality typography, such as optional ligatures, curly quotation marks, dashes, etc.
