I'm looking to know what type of fitted line the "smooth" line is when one makes a scatterplot in Scatr. It seems to be a Loess regression, but does not specify. Hope someone can clarify

Hey Kaim,
I saw you asked Ravi this question on GitHub as well.
You were already there and didn't think about taking a look at the code.
Do it now:
https://github.com/raviselker/scatr/blo ... .R#L57-L58
As you can see, there is a function call
ggplot2::geom_smooth(), with the method to use.
Which method it will use can be found a few lines above (
row: 41).
Having chosen the
Smooth option for "
Regression Line", the method will be '
auto'.
This results in the
loess method and formula.
If the messages weren't purposely suppressed (
row: 43), there would be a message like this
Code: Select all
`geom_smooth()` using method = 'loess' and formula 'y ~ x'
Cheers,
Maurizio

Salve Maurizio,
Grazie tanto per la riposta. I thought to ask here too since there didn't seem to be much activity on Ravi's Github page. Thanks very much for the clear explanation to someone new to Jamovi!
Best,
Kai
