Hi everybody! I'm Andrew Gard, a professor of mathematics and computer science at Lake Forest College, just north of Chicago, USA, where I teach statistics in R to beginning, intermediate, and advanced students. I started this channel because I believe that statistics and data science can be empowering and liberating for everyone.

Imputing missing bikeshare data with R

According to the Bikeshare data set, there was never an hour in 2011 when no bikes were rented in DC, even at 4am on the coldest night of the year. Why? Because zeros have been omitted from the set.

Is a vector the same as an array?
Mostly yes, but we don't call it that in R.
Now I finally understand what 'loess' is doing. Thanks for the video!
Here 3 hours before interview
Equitable Equations, great video keep it up bro
Awesome vid! I've used loess but never dig into it this deep. Brilliant.

good video mclovin
Thank you guru ji ❤
Very clearly explained, thank you.
Wow I was totally impressed. I am just starting to learn and was confused but you really helped me feel more comfortable using R. Thank you I look forward to learning more from you.
Very nice. I have been testing the mlr package for modeling - it is a lot more complex than tidymodels but might be more powerful.
Thank you so much- took an entire class with R and this explained it better!
where i get ""modeldata""
Error in `cols_label()`: ! Named arguments are required for `cols_label()`. Backtrace: 1. ... %>% tab_stubhead(label = "Species") 14. gt::cols_label(., count ~ "Count") Error in cols_label(., count ~ "Count") :
So under the hood, is some numerical method like gradient decent used to find the MLE of the parameters of the model?
I'm sure you're right, though I haven't researched exactly how R implements the numerical optimization.
Yeah, just a guess on my part. Been studying MLE in general lately, but so far only closed form stuff like the binomial and Poisson distributions. Just trying to get a handle on how the technique works.

How to get a box plot with categorical variable and sp richness and abundances box plots side by side. So x axis has categorical variables, but x axis has two variables box plots 😅
HI! Try using your two categorical variables with x and fill aesthetics. Should work!
Hello! Thank you so much for this its really clear and helpful! so i was wondering, lets say i want to know if 5 kinds of animals randomly locate in 5 places or they are associated with the crops, I do this test and get a p-value, can i pairwise and continue see what exact crop associate with the carcasses? I dont know whether the pairwise is for independence test or for homogeneity test
Thank you so much
Amazing video! Thank you for this great tutorial
First of all, thank you for this video. While i was arguing with one of my dc friends we threw each other tons of insults but nothing hit more than hearing "YoU'vE nEvEr eVeN HEaRd of R bEfOrE?! You KnoW wHat, PYTHON is eNouGh fOr yOu." After that i got so mad aaand we don't talk anymore ofc but my point is i felt like I should know R even though I'm not studying on data analysis. (ex-friend's department is economy and he tried to insult me who already code in c++ & python and candidate of a genetics engineer... Life's though ) Anyway long story short, with this video I learned a lot of quality information with pleasure and kinda get my inner-revenge.😇
how do we proceed if the sample size for "Type of volunteer" is different in each case and the available data is in percent form ?

Thank you!! 👍
jesus you talk way too damn much. literally just get to it. you talk WAY too damn much
nice presentation and awesome
Took a stats class in college and my professor was not good at explaining things. You on the other hand give great examples. I appreciate it very much! Wish I would have had you in school
Very well explained, excellent teacher👌
Thank you so much for these videos ive learnt so much in such a short time!
It’s probably just me not but in case anyone got stuck when trying to add total employed rn, remember to use backticks not quotes!
Could somebody please explain to me why no one explains this like third m this?! Wow, this is about as clear and understandable as anything as I have ever seen! I've tried teaching this for 25 years without ever hitting on this. Amazingly clear and accessible. Thank you

Is the there an updated tutorial? Lots of the packages are not value. IE: library(tidyverse)
Great video! Btw I did the exact same code for "Litchfield" and "Litchfield County" and the graph has a value missing for the 40-64 age group, year 2040 for Litchfield, with an error message "Removed 1 rows containing missing values" even though there IS a value for this in the dataset and also there is a point for where the supposed missing data is displayed as a point on the graph, however the annotation doesn't come up. Not sure why? I have tried it on New Haven and New Haven County and it worked fine population_projection_plot( town_to_plot = "Litchfield", county_to_plot = "Litchfield County" ) + geom_shadowtext( data = population_projection %>% filter(location == "Litchfield"), bg.color = "white", nudge_y = 0.03, aes( label = pct_formatted ) )
Do you know packages to transform data frames to latex format
Hi! Quarto will render to LaTeX ;)
What is geom ?
I'm grateful for this lesson 😃👍 Have you ever worked with ggobi and rggobi to explore multidimensional data? If so what was your take on it?
good
It was fun to have 2 simuntaneos lives over here!
It was fun to watch three of my favorite R-experts in one single RUclips session.
Can the shadowtext be pushed a distance from the line without overlapping? Having the text overlap a line makes it harder to distinguish already overlapping lines.
Love all of your channels!
I am not able to access the Carseats datasets.
Ну.... ничего страшного.

Awesome Video! How could I add margin text on a bar chart? I keep getting error "plot.new has not been called yet" when using mtext
thank you very much! very good material
