WebApr 10, 2024 · The goal of logistic regression is to predict the probability of a binary outcome (such as yes/no, true/false, or 1/0) based on input features. The algorithm models this probability using a logistic function, which maps any real-valued input to a value between 0 and 1. Since our prediction has three outcomes “gap up” or gap down” or “no ... WebMar 22, 2024 · y_train = np.array (y_train) x_test = np.array (x_test) y_test = np.array (y_test) The training and test datasets are ready to be used in the model. This is the time to develop the model. Step 1: The logistic regression uses the basic linear regression formula that we all learned in high school: Y = AX + B.
