Hello, I’m analyzing some data and I have seemingly contradictory results. I’m 
hoping someone can comment and make sense of this:

For a number of randomly selected trees, fruit drop was recorded starting late 
summer until harvest. For each tree, we recorded total fruit drop (and weight), 
harvested fruit (and weight) and the total (drop + harvest). As I was looking 
at the data, I noticed average harvested fruit size (weight/number) was related 
to Total fruits per tree… Nothing strange, until I realized harvested fruit 
size INCREASED with Total fruit number on tree. As if the fruit dropping left 
more energy for the remaining fruits to grow?

I was expecting harvested fruit size to be smaller on trees that had more total 
fruit, not the other way around.

I’m not sure this late natural fruit drop can be compared to very late hand 
thinning, but does anyone know if fruit size increase can be linked to late 
thinning (notwithstanding total yield that can go down)?

Maybe this is “normal”?

Any comment welcome!

Vincent

Like most of the data I deal with, I'm best described as either "zero inflated 
Poisson", or "zero inflated negative binomial". Anything but "Normal".

To call in the statistician after the experiment is done may be no more than 
asking him to perform a post-mortem examination: he may be able to say what the 
experiment died of.
