Choose the correct statements for logistic regression:

1. Pearson's correlation coefficient could be used for moel evaluations statistics in some classification problems.

2. If the decision boundary in a classification problem is overly complicated, the model might not generalize well.

3. We can use mean squared error in the case of logistic regression for comparison.

4. Accuracy is a good criterion for model evaluations in all kinds of classification problems.

5. The logisitc function has only one point of inflection.
