No clear difference between theoretical and empirical correlogram
ErickChacon opened this issue · comments
In the following paragraph of the introduction of chapter 10:
The sample Pearson correlation coefficient studied as a function of the lag $h$
is known as the **correlogram function**. For example, consider the exponential
correlogram function given by $cor(h) = \exp(-h)$:
The first sentence is defining the empirical correlogram function, but the example is providing a theoretical correlogram function. Maybe add a sentence before the example to present the theoretical correlogram? Or remove the word sample to refer to the theoretical correlogram?
Awesome feedback @ErickChacon. Fixing it.
I've removed the "sample" reference as suggested. Regarding the plot, do you have suggestions to make the context more clear?
At the begining of variography subsection, I would start presenting the definition of the theorerical variogram which is
After reading the text again and again, I couldn't find a simple way to distinguish theoretical from empirical variograms without assuming a more advanced mathematical background from readers. The potential of confusion doesn't pay off, and so I will close the issue for now.
If you come up with a better phrasing or note, please feel free to submit suggestions. I think the text is clear enough as is for the intended audience.
Thanks for the awesome feedback as usual.
