##### Identify and replace outliers and missing values in a time series

Uses supsmu for non-seasonal series and a robust STL decomposition for seasonal series. To estimate missing values and outlier replacements, linear interpolation is used on the (possibly seasonally adjusted) series

- Keywords
- ts

##### Usage

`tsclean(x, replace.missing = TRUE, lambda = NULL)`

##### Arguments

- x
time series

- replace.missing
If TRUE, it not only replaces outliers, but also interpolates missing values

- lambda
Box-Cox transformation parameter. If

`lambda="auto"`

, then a transformation is automatically selected using`BoxCox.lambda`

. The transformation is ignored if NULL. Otherwise, data transformed before model is estimated.
