| Fetal movements {DDPM} | R Documentation |
The data represent the number of movements made by a fetal lamb
Description
The function gives the number of movements made by a fetal lamb.
Usage
data_fetalm
Arguments
data_fetalm |
A vector of (non-negative integer) count values. |
Details
The data correspond to a certain order of counts in a study of fetal lambs' breathing and movement patterns to look at potential changes in the amount and pattern of fetal activity throughout the last two-thirds of gestation. Recently, they were used by Zhang et al. (2016) and fitted by the zero-and-one inflated Poisson distribution.
Value
data_fetalm gives many movements made by a fetus during the last two-thirds of gestation.
