NettetViewed 991 times. 4. I want to create a linear regression model to predict an output that uses two different coefficients based on some threshold within the data. For example: df: Value Temperature 8.2 70 3.2 51 5.8 54 7.2 61. and so on. For this data, I want to figure out how to make the following model: Value = B0 + B1 (HighTemp) + B2 (LowTemp) Nettet14. jun. 2024 · The reason behind 0.5. In binary classification, when a model gives us a score instead of the prediction itself, we usually need to convert this score into a prediction applying a threshold. Since the meaning of the score is to give us the perceived probability of having 1 according to our model, it’s obvious to use 0.5 as a threshold.
