Description

expSmoothMod Add a column of the smoothed values using exponential smoothing

Usage

expSmoothMod(DF, InVar, OutVar, alpha = "guess", beta = "guess", Filter = NULL)

Arguments

`DF`	The DF we are to add a exponential smoothing column to
`InVar`	The column to be smoothed
`OutVar`	The name of the new column
`alpha`	The alpha fed into forecast exponential smoothing. if it equals "guess" then it if found using parameterGuess
`beta`	The beta fed into forecast exponential smoothing. if it equals "guess" then it if found using parameterGuess
`Filter`	Prefilter using the value of a Filter col

Value

A DF with an extra col with a exp smoothed version of InVar

Examples

data("Example_data", package = "Covid19Wastewater")
Example_data <- Example_data[Example_data$site == "Green Bay",]
expSmoothMod(Example_data, "N1", "expN1")
