Use the hold-out cross-validation method to compare the accuracy rates of the linear probability model with the logistic regression model using the first 30 observations for training and the remaining ten observations for validation. (1 point for accuracy rates for the two models, 1 point for executing the linear probability model, 1 point for executing the logistic regression model, and 1 point for dividing the data into training and validation sets = total 4 points)
