mid-60's lady here thrown into Stats doing an MSc in psychology and getting a bit of a shock as this is my first module! THANK YOU! So helpful. I was overwhelmed before this. Fantastic teaching. I teach maths to struggling learners and really appreciate great teaching like yours. Being an expert in a subject does not necessarily equal a great teacher. Great teachers need to understand they are teaching something to people that probably don't get it! Good luck with your teaching and any other pursuits! I am off to Australia next week for a long break, love it there. I will be sharing this with my online classmates.

All the best

Mid-60s ? Wow you are an inspiration to me. I just started Data Science and to think that 50yrs was too late for me! Thanks

In just 40 minutes, this video provides a comprehensive overview of a whole semester's course, delivered with clear and direct explanations. Unlike my professor, who becomes upset when students seek clarification, this video addresses all my concerns about regression. I am grateful to Justin for creating this video and many others, as they have been immensely helpful. May God bless you, Justin, and keep you safe. Sending my respect and love from Germany.

Dude, my econometrics teacher is the same, or should I say econometrics presenter. First 4 lessons, some 6-7 hours of sticking to repeating the book and not allowing questions has been entirely fruitless. This video is excellent though.

[@TheAlgorithmicJourney]

If a professor gets upset because of students seeking clarification, then he or she shouldn't be a professor in the first place.

[@Abzarad]

I am no longer intimidated by these Greek letters! The thin line between complex math and useful and practical stats is dealt with elegantly. Truly grateful!

[@aklilugezahegn7187]

Witnessing an amazing precise progress over the past ten years . Missed u a lot and happy to see u are coming back.

[@oashe1]

It's a shame I discovered this channel only yesterday. My final exam is tomorrow lol. You are simply amazing, everything is on point and easy to understand. Thank you!

[@frankdunaway7744]

Thanks for the new RA video. Great reboot of your first RA lesson. I'm watching for my own benefit. No academic pursuit beyond sharpening the saw. Your explanations and examples make this material really interesting and lot easier to absorb than other channels I've watch. BRAVO! zedstatistics

[@avinashyadav_]

Love your explanation bro, you know what to include and what not to maintain the groove throughout. You deserve a lot.

[@gabriellyberg7252]

Wtf what are the odds that I have a regression lecture (that I skip to watch your content instead) 20 minutes after you upload this video? Actually insane

[@TheNachoDaddy]

Sounds like you need to rewatch the video on probability 😂. All joking aside, I hope you did well in the course (or maybe used that luck to buy a winning lottery ticket).

[@gabriellyberg7252]

Haha, nah i passed! Just a strange feeling to have the exact lecture i was supposed to have in person digitaly right as my actual lecture were ​@@TheNachoDaddy

[@paparokauli]

You love what you are doing and thats why your content is superior! THANK YOU for your contribution to free knowledge!

[@remembermyname7604]

The Regression King is back. your videos are so good.

[@AleksiRants]

What a great explanation for how adding variables affects your model! I've never even seen this considered in any of the material I've been reading and watching when learning about regression.

[@nl7247]

I watched your first video on regression when I started learning this, and this video, both are helpful and clear. Thank you so much for your videos ❤

[@rokaskarabevicius]

Old ones are absolute gems, especially "regression assumptions explained"!

[@Qongrat]

Wow, this is amazing - I am taking undergrad econometrics at uni and the lectures there seem to be just random (pun intended) stuff thrown together, you Sir, on the other hand, have an amazing structure and logical progression with a clear simple practical example. This video does an amazing job in less than 40 minutes on what they waffle about for 4.5 hours and still leave you confused. Thank you so much!

[@88pianissimo90]

Great video. I am an SAP consultant working in finance reporting and trying to learn ML. This is one of the best videos. Thank you so much for sharing this knowledge.

[@dees377]

Great content; helped me a lot to better understand regression for my CFA exam. You’re a spectacular teacher and I enjoy your videos. 😊

[@emiliyadoncheva-tzivanopou8723]

Thank you Justin so much for helping people in this difficult for me subject!!! 😊I have upcoming exam and I am so so thankful that I have the chance to hear your clear plain explanation. I think you are the most brilliant teacher. I had no idea of maths, statistics etc and thanks to you I am feeling so much confident day by day 😊

[@brunomarsh8327]

Thanks so much Justin, watched your old video at the start of my revision period, now using this one as revision, such a treat.

[@jhamdan2012]

That was awesome. The best explanation I have ever encountered regarding regression analysis.

[@loa9189]

I was literally sobbing before this video because i thought id never understand this after watching my professor's video but wow. thank you so much. I didnt even understand this using very well-known and trusted channels. I just found your channel and I'll never stop coming back for more stats and videos. I hate stats but this made me genuinely interested to learn more and have a newfound curiosity for the subject (that i never thought id have since high school_. thank you a million times.

[@dukeislam6293]

Your students are very fortunate to have a great teacher as you!

[@ScottsAwatchin]

I've seen several explanations of these concepts. This is the first time it's really started to click. Need to check out your other videos now. Great stuff. Thanks.

[@victorbegnini5754]

Man, I gotta make sure I leave you a BIG THANK YOU for your efforts and availability to share your knowledge with us. I'm new to this field and it's hard to find good "beginner-friendly" content. There's lot of videos out there. But just a few compare to yours! Thanks again! Cheers from Portugal!

Welcome back sir 🎊

[@anabelsa]

Thank you for the excellent explanation! You are such a good teacher. Just as an idea for future videos, some case studies would be very useful. Just taking a bunch of data and follow the whole process and the interpretation of what everything means. That would be very helpful for me, and I guess for everybody else.
