Run Multiple Regression from Business Manager

General
1

I'm trying to run Multiple regressions from metrics pulled out from Facebook Business Manager. However, since I'm not an experiences R user I have problems with converting data from the Excel report in order to be able to run a regression model.

I'd be really happy if someone is able to solve the struggles I have here ↓

my_data <- read.csv(file = "clipboard",
                    sep = "\t", header=TRUE)

#I can see here that my data have different classes. E.g. some are integers and some are characters 
lapply(my_data,class)


#Trying to convert all to numeric
my_data <- as.numeric(as.character(my_data))

#getting now the error
Warning message:
NAs introduced by coercion

I have been trying to first convert all to factors e.g.:
my_data <- read.csv(file = "clipboard",
sep = "\t", header=TRUE,
colClasses = "factor")

But here when trying to convert
my_data <- as.numeric(as.factor(my_data))

Then I almost all of my data removed.

I will eventually like to be able to run simple models as:

#Navngiver vores datasæt: 
"ROAS" <- my_data$Purchase.ROAS..Return.on.Ad.Spend.
"Clicks" <- my_data$Link.Clicks
"AmountSpent" <- my_data$Amount.Spent..DKK.
"PostReactions" <- my_data$Post.Reactions


#model
ROASModel <- lm(ROAS ~ PostReactions + AmountSpent)


#stargazer
stargazer(ROASModel, type = "text")

It sounds like we need to see some of your data. It looks like you are trying doing too many data conversions. This command as.factor(my_data) looks very strange.

Can you point us to it at the Facebook Business Manager or supply the data you have in the data.frame my__data?

A very simple and very effective way to supply some data is to use the dput() command.

dput(mydata)

and then simply copy the output and paste it here. If you have a very large data set then a sample should be fine. To supply us with 100 rows of your data set do

dput(head(mydata , 100))

where mydata is the name of your dataframe or tibble

Hey - of course. I have the data here using dput ↓

First silly question, is the "," a decimal separator or a thousands separator?

It seems to be turning the first variable Amount.Spent..DKK.
and the last variable * Purchase.ROAS..Return.on.Ad.Spend.* into character variables which does not look like what is intended.

I converted your data to decimal separator "." and all seems well but I did not try it in stargazer.

# rename columns to something simple
names(my_data)  <-   c("amt", "react", "engage", "clicks", "cart", "purchase", "roas")

# crude but effective way to convert to . vs , as decimal seperator. There must be a better way!
write.csv2(my_data, "~/RJunk/mount/mntdata1.csv", row.names = FALSE)

my_data  <-  read.csv2("~/RJunk/mount/mntdata1.csv")

ROASModel <- lm(roas ~ react + amt, data = my_data)
 
ROASModel

Thanks, the "," is a decimal seperator :slight_smile:

Good, looks like we are in business. I have very seldomly dealt with comma delimited variables as you can probably see from my crappy code. Here is a link to an article you may find useful.

Best wishes,
John
