+ +The sum of products is defined as + + + +```math +s = \sum_{i=0}^{n-1} x_i y_i +``` + + + + + +
+ + + +
+ +## Usage + +```javascript +var incrnansumprod = require( '@stdlib/stats/incr/nansumprod' ); +``` + +#### incrnansumprod() + +Returns an accumulator `function` which incrementally computes a sum of products, ignoring `NaN` values. + +```javascript +var accumulator = incrnansumprod(); +``` + +#### accumulator( \[x, y] ) + +If provided input values `x` and `y`, the accumulator function returns an updated sum. If not provided input value `x` and `y`, the accumulator function returns the current sum. + +```javascript +var accumulator = incrnansumprod(); + +var sum = accumulator( 2.0, 3.0 ); +// returns 6.0 + +sum = accumulator( 1.0, -1.0 ); +// returns 5.0 + +sum = accumulator( NaN, NaN ); +// returns 5.0 + +sum = accumulator( 3, NaN ); +// returns 5.0 + +sum = accumulator( 3.0, 4.0 ); +// returns 17.0 + +sum = accumulator(); +// returns 17.0 +``` + +
+ + + +
+ +## Notes + +- Input values are **not** type checked. If non-numeric inputs are possible, you are advised to type check and handle accordingly **before** passing the value to the accumulator function. +- For long running accumulations or accumulations of large numbers, care should be taken to prevent overflow. + +
+ + + +
+ +## Examples + + + +```javascript +var randu = require( '@stdlib/random/base/randu' ); +var incrnansumprod = require( '@stdlib/stats/incr/nansumprod' ); + +var accumulator; +var v1; +var v2; +var i; + +// Initialize an accumulator: +accumulator = incrnansumprod(); + +// For each simulated datum, update the sum-product... +for ( i = 0; i < 100; i++ ) { + if ( randu() < 0.2 ) { + v1 = NaN; + v2 = NaN; + } else if ( randu() < 0.3 ) { + v1 = NaN; + v2 = randu() * 100.0; + } else { + v1 = randu() * 100.0; + v2 = randu() * 100.0; + } + accumulator( v1, v2 ); +} +console.log( accumulator() ); +``` + +
