Hi folks,
I have this problem at hand:
Suppose I went to 10 lakes. I want to measure the relation with water
temperature (WT) and air temperature (AT). So I can do a regression with
these 10 points like this:
| *
| * AT
| *
|__*__________________
WT
However, to be sure, I took 3 AT's and 3 WT's at each lake. Now any
particular AT is not correlated with WT. Instead, they are kind of have
error in both X and Y axis. Can somebody show me a better way to analyze
this? I prefer talking in SAS or SAS macro.
Here is hypotheticall data sheet.
Lake, WT, AT
Lake1 10 15
Lake1 11 14
Lake1 12 13
...
Notice there is no relation between WT and AT reading. I can record this
way too:
Lake, WT, AT
Lake1 10 13
Lake1 11 14
Lake1 12 15
...
Thanks in advance.
Best regard,
W
