  2. Mulliken population analysis - Wikipedia

    en.wikipedia.org/wiki/Mulliken_population_analysis

    Mulliken charges arise from the Mulliken population analysis [1] [2] and provide a means of estimating partial atomic charges from calculations carried out by the methods of computational chemistry, particularly those based on the linear combination of atomic orbitals molecular orbital method, and are routinely used as variables in linear regression (QSAR [3]) procedures. [4]

  3. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4]

    Goma has a population of around two million and is the provincial capital of North Kivu in the eastern Democratic Republic of the Congo (DRC), being the largest city in the province. [ 26 ] [ 27 ] The Rwandan-backed rebel group March 23 Movement (M23), as part of their military offensive which has been ongoing since 2022, seized large amounts ...

  5. Mark and recapture - Wikipedia

    en.wikipedia.org/wiki/Mark_and_recapture

    The capture probability is often defined as a two-variable model, in which f is defined as the fraction of a finite resource devoted to detecting the animal or person of interest from a high risk sector of an animal or human population, and q is the frequency of time that the problem (e.g., an animal disease) occurs in the high-risk versus the ...

  6. Method of moments (statistics) - Wikipedia

    en.wikipedia.org/wiki/Method_of_moments_(statistics)

    In statistics, the method of moments is a method of estimation of population parameters.The same principle is used to derive higher moments like skewness and kurtosis. It starts by expressing the population moments (i.e., the expected values of powers of the random variable under consideration) as functions of the parameters of interest.

  7. SAAM II - Wikipedia

    en.wikipedia.org/wiki/SAAM_II

    The PC version was released in 1994. Through several grants, in the 2000-2012 period, Foster and Vicini worked on generating the modern version 2.1, including a population analysis add-on called popKinetics. In 2012, the Epsilon Group, a Medical Automation Company in Virginia licensed the commercial rights to improve and distribute the software.

  8. Density estimation - Wikipedia

    en.wikipedia.org/wiki/Density_Estimation

    The unobservable density function is thought of as the density according to which a large population is distributed; the data are usually thought of as a random sample from that population. [1] A variety of approaches to density estimation are used, including Parzen windows and a range of data clustering techniques, including vector quantization.

  9. Nucleotide diversity - Wikipedia

    en.wikipedia.org/wiki/Nucleotide_diversity

    Nucleotide diversity is a concept in molecular genetics which is used to measure the degree of polymorphism within a population. [1]One commonly used measure of nucleotide diversity was first introduced by Nei and Li in 1979.
