Arguments

x

A univariate time series as either a ts object or a vector.

frequency

The frequency associated with the time series

dates

The dates associated with the time series. This is needed for the package anomalize. If not explicitly set dates are set at a frequency 1 ending on the system date.

Value

A list with the following components:

outliers

The outliers detected, repeated if detected by multiple outlier methods.

forcastOut

tsoutliersOut

The outliers detected R package tsoutliers.

otsadOut

outmat

A matrix containing zeros and ones, with ones representing time points identified as outliers from different methods.

Examples

# NOT RUN {
set.seed(100)
n <- 500
x <- sample(1:100, n, replace=TRUE)
x[25] <- 200
x[320] <- 270
df <- data.frame(timestamp=1:n, value=x)
plot(ts(df$value))
out <- uv_tsout_ens(x)
out
