Hello
I want to predict wing length using regression commands. (lm and predict)
The data details are as followed
Data:
Bird physiological data
1. body mass
2. body length
3. wing length
Data type:
Order A: consisting of 20 species,
body mass and length of all 20 species are measured
Order B: consisting of 2 species, body mass and length of only 1 species is
measured
Order C: consisting of 5 species, body mass and length of only 1 species is
measured
Method:
1. for order A, using predict and lm
datam.lm <-lm(Wing.Length~Body.mass+Body.Length)
However, for order B and C, please kindly advise any method to get wing
length based on body mass and length.
(phylogenic relationship is tentatively neglected)
Thank you
Elaine
