I am trying to use ARIMA Algorithm for the analysis of data but as I can see the in Expert Analytics there is no Auto Arima Algorithm is available but in R it is available. so is there any possibilities to import this algorithm to expert analytics? if yes then how?

Hello Sunny,

Have you considered the automated approach to forecast a time series? I find this very efficient. It can take extra predictors into account (ie weather). And our Predictive Factory can mass-produce and mass apply segmented time series models.

Here is a tutorial to forecast a single time series with the automated approach

But to answer your question, here ist a component that uses Auto Arima. It's a pretty complex R extension and I created it before we had the Automated mode. Please see if automated works better for you:
