Gabbs: Dimensions of fetal metacurpals and phalanges

In pvrank: Rank Correlations

Description

Micrometric measurements of optically-projected histological hand sections.

Usage

data(Gabbs)

Format

A data frame with 19 observations on the following 6 variables.

V15-29mm

Absolute measurements in millimeters.

V30-44mm

Absolute measurements in millimeters.

V45-59mm

Absolute measurements in millimeters.

V60-74mm

Absolute measurements in millimeters.

V75-89mm

Absolute measurements in millimeters.

V90-104mm

Absolute measurements in millimeters.

AR

Adult ranks.

Details

Bone-to-bone ratios or proportions derived from these measurements evidence a very early disproportionate elongation of distals followed by a gradual approximation of adult proportions by the 90-104 mm crown-rump length. Adult ranks calculated from Garn et al. (1972).
