WebEssentially, I have a very low MSE, but the R^2 turns out to be negative. Even the scatterplot shows that a horizontal line isn't a good fit, so I'm not sure what to make of … WebApr 12, 2024 · The latter were calculated as the day which had the highest median value divided by the total number of sampling days (“Days”). If the first day was the hottest of nine sampled days, for example, the value would be 1/9 (details in Table 1). We added the categorical variable “Sess” (i.e., June or August) to account for potential seasonal ...
