Internal function to get centered cp objects

Needed a function for this because we do it twice: once for regional RRs and once for BLUP

Usage

get_centered_cp(
  argvar,
  xcoef,
  xvcov,
  this_exp,
  x_b,
  global_cen,
  cen,
  exposure_is_factor
)

Arguments

argvar

the list of argvar elements used to determine the exposure dimension of crossbasis

xcoef

the centered basis coefficients that resulted

xvcov

the variance covariance matrix for the centered basis coefficients

this_exp

a vector for the exposure

x_b

a list that is the boundary of this_exp

global_cen

a global centering point, if it exists

cen

the local centering point

exposure_is_factor

logical, if exposure is a factor

Value

a list object, with the centered basis and centered crosspred output

Examples

if (FALSE) { # \dontrun{
# after running condPois_1stage on a single geo_unit:
result <- condPois_1stage(exposure_matrix, outcomes_tbl)
centered <- get_centered_cp(
  argvar = result$`_`$out[[1]]$argvar,
  xcoef = result$`_`$out[[1]]$coef,
  xvcov = result$`_`$out[[1]]$vcov,
  this_exp = result$`_`$out[[1]]$this_exp,
  x_b = c(0, 40),
  global_cen = NULL,
  cen = result$`_`$out[[1]]$cen,
  exposure_is_factor = FALSE
)
} # }
