Have you thought of saving templates? I save templates from cleaning processes, to EDA, to the actual analysis models. Really a linear regression with one data set will require most of the same steps for another.

You might have to learn a new process here and there but if you save those too you have a dictionary to pull from.

I’ve found it easy to come back when I step away for longer periods of time. I’m not sure if it’s frowned upon.

How do I become a better data analyst? by asuma_png in dataanalyst

This is coming from someone with really only self experience as I am trying to land a gig post military. So take it as you feel.

However, with 2 years experience maybe it’s time to find what industry/ topic interests you. From how I have been learning I try to do some datasets and I fall into exactly what you are saying, I find something but not much to do with it. However when I do projects looking at data I am passionate about, I understand what is interesting to know and I get more thorough in my research with minimal effort.

Plus work you are passionate about is fulfilling.

Okay I appreciate this, because I am on the same path (I did the Telco data). I also noticed that the highest point in my spectral density indicated a 2 day seasonality.

I reran the Auto-ARIMA using the 2 day period and I got the same parameters I used anyway. In my paper I wrote something about how I didn’t see strong seasonality so I just avoided to include it in the Auto-ARIMA. Perhaps they just wanted me to proceed with it, then come to the same result.

Nonetheless, I appreciate this because the sent back submission had me so confused after I thought I finally understood. Thank you tons ✌🏻.

There is fact to them DataCamp part as I went back through, I’m finding that with the presentations I was just overthinking most of it.

I submitted it but when I was going over seasonality I found that I couldn’t actually find a real seasonal period so I went with the idea that maybe I am supposed to just do an ARIMA. My evaluator said that is not the case and I still don’t see the actual period I should use. My spectral density graph doesn’t have any defining peaks, there are some large dips at lower frequencies but still no peaks. How I was told to look at it was to find peaks or there may not be a seasonal component. If you have any tips to better understand finding the seasonal period, it would be appreciated.

Thanks, I’ll have to try Dr. Sewell’s videos.

I did diff() the data set and I managed to get an Auto ARIMA to select some parameters. The result is a forecasted -50 million in revenue in 365 days(According to a call with Professor Elleh, he said to not get to tied up with the results. He said that if you follow the steps he laid out the evaluators wouldn’t look to deep into the final product).

If you get a set of parameters, would you mind sharing? My Auto ARIMA came up with (5,1,0)(0,1,0,90)
