In the last post, I have explained the d value for model ARIMA (p,d,q). In this post, I am going to show how to identify the p and q values as below. one of the main difference between exponential smoothing and Arima is that Arima considers the correlation of a value at a time with Read more about Time series Series with Power BI- Arima Model-Part 11[…]
I was interested in generating some dummy data to do some load testing in MS Azure and came up with a pretty nifty way to generate lots and lots of data using U-SQL. The tip is to simply create a small U-SQL custom generator and use it to extract from a dummy file. First I Read more about How to generate 1 billion rows using U-SQL[…]
