class pyPhenology.models.ThermalTime(parameters={})

Thermal Time Model

The classic growing degree day model using a fixed threshold above which forcing accumulates. Event happens on \(DOY\) when the following is met:

\[\sum_{t=t_{1}}^{DOY}R_{f}(T_{i})\geq F^{*}\]

t1 : int

\(t_{1}\) - The DOY which forcing accumulating beings

T : int

\(T\) - The threshold above which forcing accumulates

F : int, > 0

\(F^{*}\) - The total forcing units required

Methods

__init__([parameters])
fit(observations, temperature[, method, …])	Estimate the parameters of a model.
get_doy_fitting_estimates(**params)
get_error(**kargs)
get_initial_bounds()
get_params()
predict([to_predict, temperature, doy_series])	Predict the DOY given temperature data and associated site/year info All model parameters must be set either in the initial model call or by running fit().
save_params(filename)	Save the parameters for a model
score([metric])
