Package Exports
- flow-variance
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (flow-variance) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
flow-variance
Reduce transform stream which calculates the sample variance over a stream of numeric data.
Installation
$ npm install flow-varianceExamples
var eventStream = require( 'event-stream' ),
vStream = require( 'flow-variance' );
// Create some data...
var data = new Array( 1000 );
for ( var i = 0; i < data.length; i++ ) {
data[ i ] = Math.random();
}
// Create a readable stream:
var readStream = eventStream.readArray( data );
// Create a new variance stream:
var stream = vStream().stream();
// Pipe the data:
readStream.pipe( stream )
.pipe( eventStream.map( function( d, clbk ){
clbk( null, d.toString() );
}))
.pipe( process.stdout );Tests
Unit tests use the Mocha test framework with Chai assertions.
Assuming you have installed Mocha, execute the following command in the top-level application directory to run the tests:
$ mochaAll new feature development should have corresponding unit tests to validate correct functionality.
