I have a working Predict function.Now it needs a much higher accuracy as the prediction is not accurate enough.Its not even close.
Is there a package or code anyone knows how to increase accuracy of the below predict function?
reprex:
# import data
setwd("C:/Users/jenny/Desktop/R Studio")
sales <- read_excel("C:file)")
sales <- ts(sales, frequency=3, start=c(2019,1))
predict(ts(sales))
