Function analyze

ArrayUtils

Analyze an array of objects with numeric attributes and provide various statistical measures and transformations.

This utility function takes an input array of objects with numeric attributes and performs a comprehensive analysis to calculate various statistical measures and transformations on each attribute. The function calculates the average, maximum, minimum, median, range, normalized values, standard deviation, sum, sorted data, and shuffled data of each attribute in the input objects. Additionally, it identifies any outliers present in the data.

Example

const salesData = [
  { product: 'Widget', sales: 1200, revenue: 24000 },
  { product: 'Gadget', sales: 800, revenue: 32000 },
  { product: 'Doodad', sales: 1600, revenue: 12800 },
  // ... and more data entries
];

const analysisResults = ArrayUtils.analyze(salesData);

console.log('Sales Data Analysis:', analysisResults.sales);
console.log('Revenue Data Analysis:', analysisResults.revenue);
// Output for sales data:
// {
//   mean: 1200,
//   max: 1600,
//   min: 800,
//   median: 1200,
//   range: 800,
//   normalized: [0, 0.5, 1],
//   standardDeviation: 328.02,
//   sum: 3600,
//   sorted: [800, 1200, 1600],
//   shuffled: [1200, 1600, 800],
//   outliers: []
// }

// Output for revenue data:
// {
//   mean: 22933.33,
//   max: 32000,
//   min: 12800,
//   median: 24000,
//   range: 19200,
//   normalized: [0, 1],
//   standardDeviation: 9375.57,
//   sum: 68800,
//   sorted: [12800, 24000, 32000],
//   shuffled: [32000, 24000, 12800],
//   outliers: []
// }
