My job requires a lot more ability/ knowledge in maths than I currently have (btw this was not specified in the job description or at the interview). Specifically I need graduate level understanding of non-linear regression and statistics. The person who has given me the job does not know how to do it, neither does anyone else in the team. I do love most aspects of my job though and I have always wanted to improve my maths. Can anyone recommend a suitable online tutor? Can I approach any online tutor - or is the knowledge of regression and statistics a specialist area? I can't sign up for a college course because I work full time and need to learn in the evening (and my local college only does maths up to GCSE level anyway).
