Refactor canopy_height vs. gdd model to be functional modeling #112

Closed rbartelme closed 3 years ago

rbartelme commented 3 years ago

Current model just estimates complex non-linear regression between canopy_height & gdd

Need to refactor to find growth curve parameters from the equation canopy_height = c/[1+a*e^-(b*gdd)]

[x] determine prior distribution for c
[x] determine prior distribution for a
[x] determine prior distribution for b
[x] test model on subset of data from season 6
[x] Pseudocode loop to subset a season by all the cultivars into a list of data frames
[x] Determine metric to find if this is the best method for cultivar per season parametrization

This is a WIP, but the preliminary stages are done. Some progress was lost when gpu06 went down.
