Thank you Caomei, I understand now. The smoking status also plays a role since that is the target variable. Drawing out trees helped clarify as well:

------Gender
------/------\
-----M-------F
----/--\-----/-\
--2Y-1N--1Y-0N

--Marital Status
------/------\
----NM---not NM
----/--\-----/-\
--1Y-0N--1Y-2N

--Marital Status
------/------\
--Widow--Not widow
----/--\-----/-\
--0N-1Y--1Y-2N

--Marital Status
------/------\
--Married--Not Married
----/--\-----/-\
--1Y-1N--1Y-1N

I don't know if anyone else noticed this but the syllabus was updated November 7.

I noticed they are now giving us two "cheat sheets" that will be available at the examination (pg 8 of the syllabus).

I am only on module 8, so i am not sure if they sample project on pg 8 of the syllabus is new as well.

Good Catch! I saw that yesterday but assumed this was for the package change (there was nothing listed in the updates section of the website). Not only are there two cheat sheets now (one for base R and one for ggplot) but they added a new sample project to the syllabus. That's going to be helpful.

Module 8 Slide 23: "At your exam there will be guidance regarding the order of analysis." Sounds like they'll tell you if they want you to use PCA or clustering on the exam and when to use it. I wouldn't use it unless they specify to do so.

Note that the sample project within the syllabus is designed to be within the 5-hour timeframe. Feels good man

Seems like module 9 is useless for people who have completed the FAP modules

Just finished reading, time to practice for the upcoming month now

For the sample project's usage of PCA, they say that "the key variables used earlier appear in PC2". In PC2, the four key variables are Age, Education, logCharity, and logIncome; however, in the final tree model, the four variables used are Age, Sage, logCharity, and logIncome. What gives?

Anyone have any insight as if they're going to be particular on whether or not you use the specific commands that they taught in the modules?

I finished going through the modules, not including the sample project yet, and I'm just learning R through other resources online and find other ways that are more intuitive to me and simpler and are derived from packages which will be available to use from the exam, and I'm wondering whether or not someone can not use the specific methods used in the modules and still do well as long as the output is good and the code runs.
