Arima Model Error

Kumarivaturi

We are getting a error called "no valid fields were selected". Is there anything wrong with the data? (We had seen previous questions similar where someone told to remove the commas of the column headers which we did, but it still isn't working) We had run it through data cleansing also but still the same error is shown.

PFA screenshots to see the problem.

Thank you.

@Kumarivaturi unless it’s just the snippet shown in your first screenshot, it doesn’t look like you have any date element in your dataset? The field you’re wanting to predict will need to be presented at regular intervals, and then you can select the output interval in your ARIMA configuration.

 

If this is static and there’s no time element involved then you may just want to use something like a linear regression into a score tool.

You don't have to have a date field for arima, it is used to sort your data. Probably give it a model name and select a field frequency first before you run.

Although as @DataNath mentioned, if you don't have any data field, time series may not be your best choice. Regression models, such as linear regression, random forest maybe more suitable.
