Hey excel showing input range must be contiguous reference, even though it has none. What to do
Thank you so much🥹

How do you triple click and Not Take a screenshot
Nice ty
thank you very much. easy to understand.
Thank you but the first example was a football scenario xD
What does it mean when I'm getting a different r-square value computed from regression analysis and from fitting a trendline in excel?
The professor should just say this and the three credit course will be a simple 1 credit course
Thankyou so mt❤
videos you posted so many years back are still relevant and helpful thanks a loy
I have tested many different methodologies but this simple well explained procedure resulted in the best forecast with lower error measuring ratios like mae and RSME ratios . I am impressed.
Thankyou you so much bro
Thanks dude, this saved me today. :)
