MetricValue

import type { MetricValue } from "https://googleapis.deno.dev/v1/adexchangebuyer2:v2beta1.ts";

A metric value, with an expected value and a variance; represents a count that may be either exact or estimated (for example, when sampled).

interface MetricValue {
value?: bigint;
variance?: bigint;
}

§Properties

§
value?: bigint
[src]

The expected value of the metric.

§
variance?: bigint
[src]

The variance (for example, square of the standard deviation) of the metric value. If value is exact, variance is 0. Can be used to calculate margin of error as a percentage of value, using the following formula, where Z is the standard constant that depends on the preferred size of the confidence interval (for example, for 90% confidence interval, use Z = 1.645): marginOfError = 100 * Z * sqrt(variance) / value
