Status Updates From The Manga Guide to Regressi...

Finally, i learned something I did not know that is applicable.

The definition of an outlier.
If the standardized residual is greater than 3 or less than-3 then the measurement is an outlier. Good to know

The only reason I understand even a 10th of this is because I've taken 3 statistics courses. This book is useless at explaining to someone who hasn't already taken them. The one character only exists to say 'oh' 'i understand' 'I'll put that in my notes'. Reading it makes me irritated.

So, if I wanted to show that there is a relationship between number of appearances and number of words spoken, I would plot that out on a scatter plot, probably with appearances on the x axis and words spoken on the y axis, and if there is a linear relationship, with a high r value, then I can say that they are positively correlated.

My middle school math teacher will be happy to know that I remembered how to add matrices and subtract matrices.

And will be disappointed to know that I forgot how to multiply them...sorry mom.

No. I am not still with you. I have no idea what that mass of numbers means.

I also don't understand the organization. Why would you go from differentiation to matrices? Isn't matrix math a lower level than differentiation? I remember learning about matrices. I don't remember differentiation

I'm going to need more scratch paper...

Dang. If you don't use it, you really do lose it. I just sat there scratching my head for 15 minutes over differentiating y=1/x.

The answer the book gave was -x^-2 all the answers online I opened to try to understand why said 1/-x^2 and I got all confused.

I forgot that those are saying the same thing...

Oh well, At least this book is helping me remember highschool math.

I feel completely vindicated for disliking these books right now.

There's a mistake on page 23. Rule 5. The Product rule at the top of the page has the equation as loge(a) +loge(b)=loge (a*b) [with all the e's as subscript]

On the bottom of the page Rule 5 is written as loge(a) +loge(a)=loge (a*b)

Where was the editor?!? That's a crucial problem!

I started reading this with the goal of being able to leave it here in Japan and not take it with me because I was so unimpressed with the same series book guide to statistics.

I am foreseeing the same set of problems. Thanks to the first chapter, I now understand WHAT an inverse function is. (not a mirror image like I conceptualized before) But I don't know why we use it. What purpose does it serve?

Best manga ever
