<div class="section-title">Call the hosted engine from <em>Python</em>, <em>R</em>, or <em>MATLAB</em>.</div>
These packages submit a prediction and wait until the forecast is ready. They do not install the engine on your machine.
Set <span class="mono">CSA_API_KEY</span> and <span class="mono">CSA_ACCESS_ID</span> in the environment. Jobs go to `https://api.csanalytics.io/v3/rbp-engine`.
Start with **Grid**. Use MaxFit when the attribute set is already fixed. Use PSR when the thresholds are already fixed too. What the methods mean: [[Functions/Overview|Functions]]. Option names: [[Settings/Options|Settings]].
