The acronym "CTR" is frequently used in CatBoost https://catboost.ai/docs/concepts/algorithm-main-stages_cat-to-numberic.html to represent a type of value. But I couldn't find what the acronym stands for. Could you please spell out the non acronym form, and provide some references to its definition?

Ctr is an acronym of click-through rate. They encode categorically features using this metric to get better results. It is quite similar to mean encoding.
I didn't get any online resource for reference.
Click Through Rate which is commonly used in advertisement industry. CatBoost was created by Yandex which makes all the profits in ads so I am not surprised they used CTR metric as an example all over documentation.
