Create an object var_inmb_diff

Description

The variance of the Incremental Net Monetary Benefit may also be calculated in a hypothetical situation when the standard deviation of costs and effectiveness in each group differ.

Usage

1
2
create_object_var_inmb_diff(sdc_ref, sdc_exp, sde_ref, sde_exp, rho,
  object_lambda)

Arguments

sdc_ref

: standard deviation of costs in the reference group

sdc_exp

: standard deviation of costs in the experimental group

sde_ref

: standard deviation of effectiveness in the reference group

sde_exp

: standard deviation of effectiveness in the experimental group

rho

: coefficient of correlation between the difference in costs (dc) and the difference in effectiveness (de)

object_lambda

: object containing the ceiling cost-effectiveness ratio or maximum acceptable cost of a unit of effectiveness. See create_object_lambda

Value

create_object_var_inmb_diff returns an object of class VAR_INMB_DIFF which inherits from the class VAR_INMB_DIRECT

See Also

create_object_var_inmb_direct to directly provide a value for the variance of the Incremental Net Monetary Benefit

create_object_var_inmb to calculate the theoretical standard deviation of the expected INB with the same standard deviation in the reference and the experimental group

## First, create a lambda object
object_lambda <- create_object_lambda (20000)
## Then, create a var_inmb_diff object
var_inmb_diff <- create_object_var_inmb_diff(sdc_ref=2100, sdc_exp=2100, sde_ref = 0.12,
sde_exp = 0.12, rho = 0.1,object_lambda = object_lambda)
