Okay, the user sent "co-variate". Let me check the translation rules again. The first rule is to translate all content into Russian. The second says if it's already in Russian, leave it as is. Third, only provide the translation, no explanations.
So, "co-variate" is an English word. I need to translate it into Russian. The term "co-variate" in statistics is often translated as "сопряженная переменная" or "сопутствующая переменная". But I should confirm the most accurate translation. Let me think. In Russian statistical literature, "co-variate" is commonly rendered as "сопряженная переменная". Alternatively, "взаимосвязанная переменная" might be another option, but "сопряженная" is more standard. I'll go with "сопряженная переменная" as the translation. Make sure there's no explanation, just the translation.
