I am trying to find the minimum value of the geom_smooth plot, I can find the value of Price_Volatility at the minimum point but I don't know how to find the corresponding value of Per_Foreign.
I've put the code and the first 20 observations of the dataset below.
ggplot(data = CD_Turnover, mapping = aes(x = Per_Foreign, y = Price_Volatility))+
geom_point() +
geom_smooth(span = 0.99)
smooth_vals = predict(loess(Price_Volatility~Per_Foreign, CD_Turnover, span = 0.99))
min(smooth_vals)
Per_Foreign Price_Volatility
