    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/datasets-berndt-cps-wages-1985
```

</section>

<section class="usage">

## Usage

```javascript
var cps = require( '@stdlib/datasets-berndt-cps-wages-1985' );
```

#### cps()

Returns a random sample of 534 workers from the Current Population Survey (CPS) from 1985, including their wages and other characteristics.

```javascript
var data = cps();
// returns [{...},{...},...]
```

Each `array` element has the following eleven fields:

-   **education**: number of years of education.
-   **south**: indicator variable for southern region (`1` if a person lives in the South; `0` if a person does not live in the South).
-   **gender**: gender of the person.
-   **experience**: number of years of work experience.
-   **union**: indicator variable for union membership (`1` if union member; `0` if not a union member).
-   **wage**: log-transformed wage (in dollars per hour).
-   **age**: age (in years).
-   **race**: ethnicity/race (`'white'`, `'hispanic'`, and `'other'`).
-   **occupation**: occupational category (`'management'`, `'sales'`, `'clerical'`, `'service'`, `'professional'`, and `'other'`).
-   **sector**: sector (`'other'`, `'manufacturing'`, or `'construction'`).
-   **married**: marital status (`0` if unmarried; `1` if married).

## Notes

-   Based on residual plots, wages were log-transformed to stabilize the variance.

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var Plot = require( '@stdlib/plot' );
var dataset = require( '@stdlib/datasets-berndt-cps-wages-1985' );

var data;
var plot;
var opts;
var x;
var y;
var i;

data = dataset();

// Extract wage data...
x = [];
y = [];
for ( i = 0; i < data.length; i++ ) {
    x.push( data[ i ].age );
    y.push( data[ i ].wage );
}

// Create a plot instance:
opts = {
    'lineStyle': 'none',
    'symbols': 'closed-circle',
    'xLabel': 'Age',
    'yLabel': 'Wage',
    'title': 'Age vs Wage'
};
