Kernel density estimation of 100 normally distributed random numbers using different smoothing bandwidths.. In statistics, kernel density estimation (KDE) is the application of kernel smoothing for probability density estimation, i.e., a non-parametric method to estimate the probability density function of a random variable based on kernels as weights.

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).
Factors affecting the width of the CI include the sample size, the variability in the sample, and the confidence level. [2] All else being the same, a larger sample produces a narrower confidence interval, greater variability in the sample produces a wider confidence interval, and a higher confidence level produces a wider confidence interval. [3]
where ¯ is the sample mean, s is the sample standard deviation, m 2 is the (biased) sample second central moment, and m 3 is the (biased) sample third central moment. [6] is a method of moments estimator. Another common definition of the sample skewness is [6] [7]
Rational Numbers Excel Add-In Proprietary: De novo identification tool for small molecules that works with Microsoft Excel (2010, 2013, 2016 and 2019). This software treats small molecules as mathematical partitions of the molecular mass and generates subfragment formulas with atoms that are sets of partitions comprising the molecular formula.
The first Archimedes models were introduced in 1987, [1] and systems in the Archimedes family were sold until the mid-1990s alongside Acorn's newer Risc PC and A7000 models. [2] The first Archimedes models, featuring a 32-bit ARM2 RISC CPU running at 8 MHz, provided a significant upgrade from Acorn's previous machines and 8-bit home computers ...
