/**
 * Create experiment
 *
 * @remarks
 * Create an experiment.
 *
 * To run this experiment, you'll need to [create an iteration](https://launchdarkly.com/docs/api/experiments/create-iteration) and then [update the experiment](https://launchdarkly.com/docs/api/experiments/patch-experiment) with the `startIteration` instruction.
 *
 * ### Experiment types
 *
 * Use the `type` field to specify the experiment type: `experiment` (default), `mab` (multi-armed bandit), or `holdout`.
 *
 * For multi-armed bandit experiments, set `reallocationFrequencyMillis` on the iteration to control how often traffic is reallocated across variations.
 *
 * ### Results analysis
 *
 * Use the `methodology` field to specify the results analysis approach: `frequentist` (default) or `bayesian`. Multi-armed bandit experiments support only `bayesian`, which is their default.
 *
 * Use the `dataSource` field to specify the source of metric data: `launchdarkly` (default), `snowflake`, or `databricks`.
 *
 * Use the `analysisConfig` field to customize analysis settings such as the Bayesian threshold, significance threshold, or multiple comparison correction method.
 *
 * To learn more, read [Creating experiments](https://launchdarkly.com/docs/home/experimentation/create).
