pool_propdiff_nw
Calculates the pooled difference between proportions
and confidence intervals according to Newcombe-Wilson (NW) across
multiply imputed datasets.
pool_propdiff_nw(object, conf.level = 0.95)
object |
An object of class 'mistats' ('Multiply Imputed Statistical Analysis'.). |
conf.level |
Confidence level of the confidence intervals. Mostly set at 0.95. |
The pool_propdiff_nw
function uses information from separate
exposure groups. It is therefore important to first use the propdiff_wald
function and to set strata = TRUE in that function.
The Proportion and the Confidence intervals according to Newcombe-Wilson.
