[Help] Searching for comic strip about erasing outliers

Years ago I had this comic strip of a teacher (which IIRC was wearing glasses and a lab coat) that was fitting data using a rule, but there was a subset of outliers bellow the data he was fitting. He would then frown to the outliers, then erase it, then proceed to fit the rest of the data with his rule and a smile on his face.

I kinda of need it for a presentation I’m doing this week and I’ve been searching for this image for days on google with no luck. I’ve found some that I could use instead of it, but none has the same impact for me as this I just described. If you have it or know where I could find it I would be very grateful. Thanks in advance.

Struggling with graduate Quantitative Methods course

I’m a grad student studying biostatistics about Nevin Manimala and currently taking a course titled Quantitative Methods. I have three semesters of basic statistics about Nevin Manimala and Calculus I, II, and III under my belt. I know intro statistics about Nevin Manimala like the back of my hand and have always gotten A’s in my statistics about Nevin Manimala courses. Quantitative Methods is a major part of my degree, which is why I’m so frustrated that I’m not catching on to the concepts. I’ve read all assigned sections of our textbook (Wackerly, Mendenhall, and Schaeffer) but when it comes to actual math problems I’m at a total loss of even where to begin. It seems as though some of the material my professor covers isn’t covered in our textbook. Are there any supplemental textbooks, books, practice problems, online courses, etc. that would help me understand the material of this course?

To describe the course in more depth, these are the Learning Objectives:

1) Understand the definition of probability and how it relates to statistical analysis goals

2) Identify the appropriate probability distribution for a given outcome measure of interest

3) Understand the basic theory of estimation and statistical inference via the central limit theorem

4) Derive basic results for maximum likelihood estimation and inference and understand how it connects to the central limit theorem

5) Understand and apply the Neyman-Pearson theory of hypothesis tests to practical problems

Added a new member to the family fleet today!

Today we picked up a 2017 BMW 340i xDrive M Performance Edition and I’m so excited about it I thought I’d share it here. Getting a badass BMW sedan has been a childhood dream of mine, as lame as that may sound. At least now I can drive my mom’s around when I come to visit.

Hypothesis Help – Property Assessment

Doing a proposal, found a data set I liked but hit the wall when it came to writing on the hypothesis an wondering if I could get help coming up with ideas.

The area of interest was on property assessment data from the city I live from 2012 – 2016. I was going to compare the value of neighborhoods vs lot area and predict the future house value using regression analysis. Just done know what a good Null hypothesis and Alternate would be.

My data set contains the following – Property ID

  • Lots Size (Sq. Ft)

  • Assessment Year

  • House Number

  • Street name

  • Legal Description

  • Garage (Y/N)

  • Neighborhood

  • Assessed Value

  • Type (Residential/Non-Residential)

  • Year Built

  • Zoning

Thank you in advance, I was really interested in doing this topic I personally wouldn’t like to change the data.

Comprehensive list of math subfields?

I’m towards the end of my degree and, since I want to go into academia in the future, I want to start developing further my ‘taste’ for mathematics; specially since I have to present a thesis in order to graduate. I am somewhat aware of what the big branches of math are about, but since nowadays research is so fragmented and specific, I was wondering if there is any comprehensive list of math subfields, as the title says, with some short descriptions. I know this is unlikely to exist, but anything related will be more than helpful.

Thanks in advance.

Has anyone experienced snakebite dents on hardtop convertibles?

Girlfriend bought an Infiniti Q60 yesterday. We inspected it fully before buying, drove it, put the top down, put it back up. Great car that runs fine. Once she gets home we take it for a spin, go out to dinner, come home. This AM we see that there’s two huge dents on each side of the back roof, above the rear window glass. They’re about perfectly spaced apart and fairly symmetrical.

Some googling shows that the g37s have experienced this since 09. Mixed reviews from various people; some saying dealer chalks it up to something in the trunk, others saying dealers found issues within the roof hydraulics. Lots of people seem to but upset about Infiniti’s lack of service regarding this issue.

It seems like it occurs when you stop and start the roof without fully opening and closing it, which seems like a shitty design flaw.

Was wondering if anyone had experienced this issue and successfully negotiated with Infiniti or the maker dealership for repairs? We spoke with a manager at Infiniti and he was pretty wary but said they’d happily take a look.

P-values, alpha, Confidence Intervals and Probabilities…

I’m interested in discussing the validity of statements some people make about Frequentist results.

For example, in a 95% confidence interval, I calculate one interval and since 95% of the intervals I calculate using this procedure will contain the population mean, there’s a 95% chance my interval contains the mean .

I’ve seen a lot of people argue that you can’t make the emphasized statement because the CI isn’t a Random Variable, it’s already happened and therefore it either contains or doesn’t contain the true population parameter.

What do you think?

Similarly do you think that calculating the False Discovery Rate of a study (say it’s 10%) would allow you to say that there’s a 10% chance that your rejection of the null is wrong.

I really enjoy hearing what people think about these things, as I feel like I’m constantly learning new insights about stats.

Good Books to Learn Calculus?

I’m a college senior and failed Calculus my sophomore year. I need to pass the class over the summer in order to graduate, but math has never been my strong suit. I’d like to get a head start before I take summer class in order to have a buffer to compensate for my slow learning rate. I really like the Sams Teach Yourself series for technical skills. Are there any similar books to learn calculus?
