Lil’ Muncher (official name lol) update:
1) LM abandoned his post at 50% consumption but
2) Found a friend, LM2
3) And many more 😵💫
Consumption rates have become exponential and sadly all (visible) Munch Bunchers had to be evicted.

Sometimes it's good to revisit the basics.
Part 1 of a series on using the binomial distribution to interpret & power studies on rare events -- inspired by Martin Bland's write-up, "Detecting a single event".
Spoiler: rare events are hard to find 😜

Better late than never — here’s my #TidyTuesday submission from last week's data!
I built a #shiny app with #plotly to explore the @xkcd.com color survey results in both 🌈 RGB and HSV space🌈.

Fair point! This fig doesn’t scream “this is gonna cause bias”.
Sex is a covariate here, but the imbalanced sampling forces it to become a confounder.
In balanced designs, you don’t have to adjust for sex to get an unbiased age estimate (but it’s less powerful).
In imbalanced designs you do.

I wrote a little post on a common issue:
You accidentally got a biased sample & now your results might biased be too.
How to recover? Can you?!

If I'm understanding correctly, you want to subset a vector of strings based on regex?
grep() setting the argument value = TRUE is pretty helpful!
#rstats

![# Example data
x <- c("apple", "banana", "grape", "pineapple", "apricot")
# Filter strings that contain "apple"
grep("apple", x, value = TRUE)

# Filter string that starts with "a"
grep("^a", x, value = TRUE)

Ooooh, I’m a fan of having the range of observed data on there!
Interactions = the effects change over the range of X — but many models predict beyond the observable range of X. For small but sig effects, if the effects aren’t sig over the observable data, then it’s not really an effect, right?
