From most recent to earliest

---

• 12 Feb: the notes for the least-squares section are posted.
• 12 Feb: weekly test 5 deadline extended to 12:15 today. A few people haven't got around to completing it.
• 10 Feb: assignment 4 will be posted this week, but the due date changed to after reading week. This is as a result of the bump in dates from the snow day.
• 08 Feb: Snow day: class for Friday is cancelled, and assignment 3 is now due on Tuesday, 12 Feb, paper or electronic, at class. No late hand-ins, we will post solutions on 12 February.
• 07 Feb: Important note: A large number of students are submitting assignments electronically, which we encourage and find easier to grade. However, you must follow the electronic submission instructions in order for us to grade your work. If you prefer not to follow these instructions, please submit in paper form instead.
• 06 Feb: quite a few emails asking if enough information is provided in assignment 3, etc. General rule: if information isn't provided, and you think it should have been, use an assumed value, but clearly justify why you've assumed the value, and why you picked the value you did.
• 06 Feb: regarding question 2 and 3 in assignment 3: the problem is sufficiently specified, it is just not obvious what you need to do. That's typical ... an industrial statistics problem doesn't present itself to you in the form: "Calculate a confidence interval ...."; you have figure out what you want to determine (the aim), and then what you need to calculate. It is an important skill to learn how to translate an industrial requirement into a statistical calculation.
• 06 Feb: the weekly tests are going well so far, so the midterm for 4C3 is cancelled.
  • Expect the grading part of the website to be ready during reading week.
  • Expect a slightly longer than normal weekly test at the end of reading week, going into the next week. That test will cover all the course material.
• 05 Feb: solutions to assignment 2 are posted (PDF).
• 03 Feb: the next weekly test is posted. You must complete it by 11:30AM on Tuesday, 5 Feb.
• 01 Feb: assignment 3 is posted; due on 08 February.

  • The problem with questions randomly being reordered has been fixed. Thanks for reporting that.

• 27 Jan: some delays with the weekly test and the server ... expect it on Monday (28 Jan).
• 25 Jan: I forgot to add in class today that if you'd like the R code for any drawing in the course textbook or slides, just send me an email with the page or slide number.
• 25 Jan: please note that class on Friday, 01 February, will be cancelled to accommodate the 4W4 students going on the XRCC plant tour (and I will be joining you).

• A good overview of understanding plotting in R is given in this YouTube video.
• 17 Jan: 6C3 students: please email me with your full name and student number. I do not get your registration information from the university. It is your responsibility to get this information to me, so that I can set you up for the weekly tests.

• Solutions for the first test are now available: sign in http://quest.mcmaster.ca/ to compare your answers. In a week or two the system will also automatically grade you (where possible); that feature isn't developed yet.
• Another interesting seminar on campus: John Bianchini, CEO of Hatch, will be talking at the free Chemical Engineering seminar on Thursday, 17 January, 10:30 to 11:20, JHE326H: moved to 28 March.
• Assignment 1 is posted; due 18 January, in class on paper, or electronically. Please do not use the Chem Eng dropbox for assignment submissions.
