Regarding the further processes, I understand that Pearson's correlation coefficient and Chi Squared tests are accepted as further math processes. But can nonlinear regression (like Logarithmic linear regression or logistic linear regression) be considered a further process as well? And if one has a strong understanding of higher level math functions but they're not in the Math Studies textbook or in the curriculum provided by the teacher, does IB penalize you for that or do they not care? Reason why I ask is because I'm doing a population forecast for the population of the United States of Am
