I didn't know statistics could make me happy but THIS LITERALLY CURED MY DEPRESSION

SMart teaching, intelligent approach, all with sense of humour; thank you for not considering us dafts! You teaching 100% worths my time, have been watching your videos several times and it does help me a lot!

Super super helpful! Ready to go through the series of your glm videos. T-test, ANOVA, and all the other so-called "statistical tests" have been bothering me for so long. The equation: "Outcome= intercept + slope*predictor +e " is just simplistic and useful!! Thank you so much for making these videos.

When I was in my math pedagogy courses, I learned that if I can’t explain something simply, I don’t really understand it yet. Thank you for doing what I have never seen another stats prof do (explain it simply).

Thank you for giving the formulas to connect the GLM with the decision tree BS. The GLM makes more sense because (for more of us than the alternative), H0: we have prior learning that we can connect GLM to. The other stats methods? Yeah… it mostly just makes the case for more stats profs to scaffold their instruction.

Hi, sorry I'm late to the party. Great video, but I have a question: Isn't measuring data in interval or ratio scale an asumption we make? Would depression score but interval or just ordinal scale? What about IQ? Thanks for your videos.
@QuantPsych
@QuantPsych Жыл бұрын
Technically we make that assumptions, but it turns out that violating that assumption isn't all that problematic. If I weren't lazy, I'd give you a reference, but I am lazy :)

@@QuantPsych Thanks for the answer. Thinking about it it is probably hidden somewhere in the linearity asumption. If the predictor scale is not linear then predicting with a linear model is probably not the right approach... Great videos btw.

I just have a kind of existential question: What are polynomials really doing when it comes to real life facts.. like how do they model stuff, what does the following equation: 4*(#of_tv_hours)^2 + 2*(#of_tv_hours) +7 have to do with real life, with what's actually happening in reality( like when someone watches the tv for one hour, 100 cells in his brain are damaged..etc that could be modelled perfectly with this but otherwise, why use that??) I know it doesn't have to be accurate but approximate enough.. so.. why does it make it approximate enough?! is everything in life related together with some polynomial out there? What's so sacred about polynomials? (polynomials are very obvious in physics/dynamics,i.e: throwing a ball upwards make it make a shape of parabola, the rule of physics are built on polynomials. But how do relations between some facts in life are related to this... and then if we could model it, how can we reduce that relationship modeled by a polynomial into a linear equations... where did the quadratic and cubic relationships go!!?? @QuantPsych

A linear model, an ANOVA, and a T-test enter to a bar and the bartender ask “are you waiting for someone or just be by yourself?” 😂 Great videos, do you have anyone explaining gls(), for instance when your data have linear relationships but not homogeneity of variation? (Note, I don’t want to transform variables because the complication of understanding slopes transformed)
