In genetics, a polygenic score ( PGS) is a number that summarizes the estimated effect of many genetic variants on an individual's phenotype. The PGS is also called the polygenic index ( PGI) or genome-wide score; in the context of disease risk, it is called a polygenic risk score ( PRS or PR score [1]) or genetic risk score.
The inaccuracy in Excel calculations is more complicated than errors due to a precision of 15 significant figures. Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x. All the values of x begin at the 15 th decimal, so Excel ...
Amniocentesis is a medical procedure used primarily in the prenatal diagnosis of genetic conditions. [1] It has other uses such as in the assessment of infection and fetal lung maturity. [2] Prenatal diagnostic testing, which includes amniocentesis, is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis ...
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS. It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA). Excel forms part of the Microsoft 365 suite of software.
Prostaglandins ( PG) are a group of physiologically active lipid compounds called eicosanoids [1] that have diverse hormone -like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are derived enzymatically from the fatty acid arachidonic acid. [2] Every prostaglandin contains 20 carbon ...
In mathematics, a continuous function is a function such that a small variation of the argument induces a small variation of the value of the function. This implies there are no abrupt changes in value, known as discontinuities. More precisely, a function is continuous if arbitrarily small changes in its value can be assured by restricting to ...
Probability mass function. In probability and statistics, a probability mass function (sometimes called probability function or frequency function [1]) is a function that gives the probability that a discrete random variable is exactly equal to some value. [2] Sometimes it is also known as the discrete probability density function.
Homothetic preferences. In consumer theory, a consumer's preferences are called homothetic if they can be represented by a utility function which is homogeneous of degree 1. [1] : 146 For example, in an economy with two goods , homothetic preferences can be represented by a utility function that has the following property: for every : In ...
