ARIMA Model woes

[aesekody]

I am trying to do a time series forecast and my ARIMA model is running the forecast from 2007 to 2100. my data spans from 2007 to 2023. I don't know what I am doing wrong.

What is your ARIMA tool configuration?

I used the standard configuration

It looks like you are doing options beyond the standard configuration since you are customizing the parameters in the "Model customization (optional)" part! 

Each line of your data is a distinct week between 2007 and 2023? Can you send a screenshot of what that looks like?

@aesekody can you provide a screenshot of the data, not the output?

[aesekody]

The dates, and counts are random. sometimes daily, and in some cases weekly.

Good to know - then I would use some sort of logic to aggregate so that the data is at the weekly level. With differing levels of time, it's likely to result in odd results.

One possible way is to identify the Sunday for each date and use that to group by while summing the numeric field. Then your weekly breakdown should be better!
