ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
simple-statistics
Advanced tools
The simple-statistics npm package provides a comprehensive set of statistical tools and functions for performing various statistical analyses. It is designed to be easy to use and covers a wide range of statistical operations, from basic descriptive statistics to more complex regression analysis.
Descriptive Statistics
This feature allows you to calculate basic descriptive statistics such as mean, median, and variance. The code sample demonstrates how to compute these statistics for a given dataset.
const ss = require('simple-statistics');
const data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const mean = ss.mean(data);
const median = ss.median(data);
const variance = ss.variance(data);
console.log(`Mean: ${mean}, Median: ${median}, Variance: ${variance}`);
Probability Distributions
This feature provides functions to work with various probability distributions, including normal and binomial distributions. The code sample shows how to generate a random normal value and a binomial distribution.
const ss = require('simple-statistics');
const normal = ss.randomNormal(0, 1);
const binomial = ss.binomialDistribution(10, 0.5);
console.log(`Random Normal Value: ${normal}, Binomial Distribution: ${binomial}`);
Regression Analysis
This feature allows you to perform regression analysis, including linear regression. The code sample demonstrates how to compute a linear regression line for a given dataset.
const ss = require('simple-statistics');
const data = [[0, 1], [1, 2], [2, 3], [3, 4], [4, 5]];
const regression = ss.linearRegression(data);
const regressionLine = ss.linearRegressionLine(regression);
console.log(`Regression Line: y = ${regression.m}x + ${regression.b}`);
Hypothesis Testing
This feature provides functions for performing hypothesis testing, such as t-tests. The code sample shows how to perform a two-sample t-test on two datasets.
const ss = require('simple-statistics');
const tTest = ss.tTestTwoSample([1, 2, 3, 4, 5], [6, 7, 8, 9, 10]);
console.log(`T-Test Result: ${tTest}`);
jstat is a JavaScript library for statistical operations. It offers a wide range of statistical functions similar to simple-statistics, including descriptive statistics, probability distributions, and hypothesis testing. However, jstat has a more extensive API and supports matrix operations, making it suitable for more complex statistical analyses.
mathjs is a comprehensive mathematics library for JavaScript and Node.js. It includes a variety of mathematical functions, including statistical operations. While it is not solely focused on statistics like simple-statistics, it provides a broader range of mathematical tools, making it a versatile choice for projects that require both statistical and general mathematical computations.
ssjs (Statistical Software in JavaScript) is another library that provides statistical functions for JavaScript. It offers similar functionalities to simple-statistics, such as descriptive statistics and probability distributions. However, ssjs is less popular and has a smaller community compared to simple-statistics, which may affect the availability of support and updates.
A JavaScript implementation of descriptive, regression, and inference statistics.
Implemented in literate JavaScript with no dependencies, designed to work in all modern browsers (including IE) as well as in node.js.
simple-statistics
module, using npm install simple-statistics
,
then include the code with require or import:require
function to use modules in my project. (most likely)
require
, you have the freedom to assign the module to any
variable name you want, but you need to specify the module's name exactly:
in this case, 'simple-statistics'. The require
method returns an object
with all of the module's methods attached to it.var ss = require('simple-statistics')
import
to use modules in my project. I'm probably using Babel, @std/esm
, Webpack, or Rollup.
import * as ss from 'simple-statistics'Include a specific named export:
import {min} from 'simple-statistics'Simple statistics has only named exports for ES6.
ss
. You can reassign this variable to
another name if you want to, but doing so is optional.
<script src='https://unpkg.com/simple-statistics@7.8.3/dist/simple-statistics.min.js'>
</script>
?module
query parameter of unpkg. If you
specify type='module'
in your script tag, you'll be able to import simple-statistics
directly - through index.js
and with true ES6 import syntax and behavior.
<script type='module'>
import {min} from "https://unpkg.com/simple-statistics@7.8.3/index.js?module"
console.log(min([1, 2, 3]))
</script>
This feature is still experimental in unpkg and very bleeding-edge.FAQs
