Basic Usage

A quick introduction to using Scientist.
The key to mastering Scientist, is learning how to define Experiments. In the introduction section, we created a basic experiment, but there's a lot more available to use. Let's take a look at a very simple experiment. [block:code] { "codes": [ { "code": "<?php\n\n$experiment = (new Scientist\\Laboratory)\n ->experiment('experiment title')\n\t->control($controlCallback)\n ->trial('trial name', $trialCallback);\n\n$value = $experiment->run();", "language": "php" } ] } [/block] That's great. We're defining an experiment with a control, and a single trial. Nothing too complicated there. Now let's take a look at a more complex example. Here we'll see more of the methods that we can use to define our experiments. [block:code] { "codes": [ { "code": "<?php\n\n$experiment = (new Scientist\\Laboratory)\n ->experiment('experiment title')\n\t->control($controlCallback)\n ->trial('first trial', $firstTrialCallback)\n ->trial('second trial', $secondTrialCallback)\n ->trial('third trial', $thirdTrialCallback)\n ->matcher(new Scientist\\Matcher\\StandardMatcher)\n ->chance(50);\n\n$value = $experiment->run(3, 'apple', $panda, 42);", "language": "php" } ] } [/block] In the above example, we are using every available experiment method. Once again, we'll get the result of the `$controlCallback` callable instance when we run the `run()` method. All of our callbacks will execute, but only the control callback's resulting value will be used. In the next section, we'll examine each of the methods above in more detail.
