This is for assignment. But i am not asking for hold my finger and guide me. Just asking something that is confusing me.
I am reading a chapter in which we are using
lindia package. The value of
mydata was calculated from
mydata <- with(my_centered_data, lm(y ~ x)).
The output of this is following graph
The author of the tutorial then went on to say that there is no
non-linear pattern here. Even though, to me, it appears that there is kind of a sin wave ..
Now, here is another graph
Should i consider that there is no pattern here as well? Or should i call it out that there are outliers at the bottom of the graph?
I mean, I am not sure why author said in first graph that it is linear and because of that i am confuse at second one
