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 // Flow variance stream generator:
vStream = require( 'flow-variance' );
var data = new Array( 1000 ),
stream;
// Create some data...
for ( var i = 0; i < 1000; i++ ) {
data[ i ] = Math.random();
}
// Create a new stream:
stream = vStream().stream();
// Add a listener:
stream.on( 'data', function( variance ) {
console.log( 'Variance: ' + variance );
});
// Write the data to the stream...
for ( var j = 0; j < data.length; j++ ) {
stream.write( data[ j ] );
}
stream.end();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:
