wght_deriv_array: Create an array of group weight derivatives
In inferference: Methods for Causal Inference with Interference

Uses wght_deriv_calc to compute the weight derivatives for each group per coverage level

wght_deriv_array(
  parameters,
  integrand,
  allocations,
  X,
  A,
  G,
  runSilent = TRUE,
  integrate_allocation = TRUE,
  ...
)

`parameters`	vector of parameters passed to `integrand`
`integrand`	function to pass to the argument 'f' of `integrate`.
`allocations`	coverage levels in [0, 1]. Can be vector.
`X`	covariate matrix
`A`	vector of treatment assignments
`G`	vector of group assignments
`runSilent`	if FALSE, errors are printed to console. Defaults to TRUE.
`integrate_allocation`	Indicator of whether the integrand function uses the allocation parameter. Defaults to TRUE.
`...`	other arguments passed to integrand.
