sensitivity_analysis: One-at-a-time PEcAn sensitivity analysis

In ashiklom/fortebaseline: Forest Resilience and Threshold Experiment (FoRTE) ED2 baseline runs source code and manuscript

Description

NOTE: Fitting all at once results in too few degrees of freedom. Need to fit one at a time.

Usage

sensitivity_analysis(
  y,
  x,
  ymedian = median(y),
  xmedian = median(x),
  alpha = 0.05
)

Arguments

y	Response variable
x	Dependent variable
ymedian	Median of response variable (default is calculated as 'median(y)')
xmedian	Median of dependent variable (default is calculated as 'median(x)')
alpha	Fraction of median around which to calculate derivative for sensitivity. Default = 0.05

Value

'tibble' of sensitivity analysis results, with columns 'cv' (Coefficient of variation for 'x'), 'sensitivity' (unnormalized sensitivity of 'y' to 'x' at median), 'elasticity' (normalized 'sensitivity'), and 'pvar' (prediction variance).
