start_ts_after_internal_nas: Start a Time Series after the Last Internal NA

In mbannert/tstools: A Time Series Toolbox for Official Statistics

Start a Time Series after the Last Internal NA

Description

Internal NAs can cause trouble for time series operations such as X-13-ARIMA SEATS seasonal adjustment. Often, internal NAs only occur at at the beginning of a time series. Thus an easy solution to the problem is to discard the initial part of the data which contains the NA values. This way only a small part of the information is lost as opposed to not being able to seasonally adjust an entire series.

Usage

start_ts_after_internal_nas(series)

Arguments

series

on object of class ts
