    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/stats-base-ztest-two-sample-results-factory
```

</section>

<section class="usage">

## Usage

```javascript
var resultsFactory = require( '@stdlib/stats-base-ztest-two-sample-results-factory' );
```

#### resultsFactory( dtype )

Returns a new constructor for creating a two-sample Z-test results object.

```javascript
var Results = resultsFactory( 'float64' );
// returns <Function>

var r = new Results();
// returns <Results>
```

The function supports the following parameters:

-   **dtype**: floating-point data type for storing floating-point results. Must be either `'float64'` or `'float32'`.

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   A results object is a [`struct`][@stdlib/dstructs/struct] providing a fixed-width composite data structure for storing two-sample Z-test results and providing an ABI-stable data layout for JavaScript-C interoperation.

## Examples

```javascript
var Float64Array = require( '@stdlib/array-float64' );

var resultsFactory = require( '@stdlib/stats-base-ztest-two-sample-results-factory' );
