Okay, the user sent "co-variate". Let me check the translation rules. First, translate into Polish. The word "co-variate" is an English term, likely related to statistics or mathematics. In Polish, "co-variate" would be "kowariancja" or "kowariata". Wait, "kowariancja" is the noun form, but "co-variate" is an adjective or noun? Let me confirm. The term "covariate" in statistics refers to a variable that is being predicted or is a factor in a model. In Polish, that's "kowariata". So the correct translation would be "kowariata". The user wants only the translation, no explanations. So the response should be "kowariata".
