This returns an error. The column in the dataset is CustomerType.

Note from the Author or Editor:

"Figure 4-15 shows the corresponding correlation matrix"

should be replaced with

"Figure 4-15 shows the corresponding correlation matrix, after renaming the variables for readability

## R
dat <- dat %>%
rename(CustTyp= CustomerType) %>%
rename(DistCh = DistributionChannel) %>%
rename(RepGst = IsRepeatedGuest) %>%
rename(MktSgmt = MarketSegment) %>%

I can't find the file chap10-experimental_data.csv. I don't see it in the GH folder for this chapter (https://github.com/FlorentBuissonOReilly/BehavioralDataAnalysis/tree/master/Chapter%2010%20-%20Cluster%20Randomization%20and%20Hierarchical%20Modeling)

Note from the Author or Editor:
The missing file has now been uploaded to Github, no need to do anything else.

1st paragraph after title "Expanding chains"

in equation DonutSales = βTTemperature
Shouldn't "beta" be with tilde, like on page before?

Note from the Author or Editor:
Chapter 3 > Fundamental Structures of Causal Diagrams > Expanding chains:
In the sentence "This causal relationship translates into the equation DonutSales = βTTemperature.", there should be a tilde over βT.
