Repeat interpolation of daily spatial data by EBK regression prediction using ModelBuilder

[KaiyuanZheng]

I use the following ModelBuilder model to perform iterating interpolation over the daily wind speed data on ArcGIS Pro. The iteration field value is Interpo: Day1, Day2, Day3......

The ModelBuilder works well when I use other interpolation methods, such as IDW or ordinary Kriging, which requires Z value field as interpolation value and I input iteration field value in it.

However when I use EBK regression prediction which requires dependent variable field as interpolation value, it can't recognize the iteration field value as input value, and error message which shows dependent variable field value is required was produced.

How can I fix this?

@KaiyuanZheng  you run the model with "skip null values" selected in the iterate field values? I think the null values are causing the error

Thanks BrendanNewell, that works for me now.
