Excel as diagnostic tool

Good morning,

I just finished the last lab in week 3 and am moving on to the second course. I did want to mention something I did when I was stuck and couldn’t get my logistic regression model to work. I reproduced the model in Microsoft Excel. This allowed me to break down my calculations and find where I had an error in my algorithm. It turns out is was a simple error, but I guess they usually are.

Anyway, just a suggestion in case you get stuck.

Best of luck,

Thank you Raymond. It was very helpful to lay it out in Excel.

BTW, that was a fantastic course, I am looking forward to the next one!

Best regards,
