predict.logitreg {analogue} | R Documentation |
Predict the posterior probability of analogue-ness between fossil and training set samples based on logistic regression fits.
## S3 method for class 'logitreg'
predict(object, newdata, group = "all", k = 1, ...)
object |
an object of class |
newdata |
an object of class |
group |
character; for which group(s) are predictions
sought. |
k |
numeric; the number of close modern analogues to each fossil
sample to consider. Not currently used and may be removed from the
method as varying |
... |
additional arguments passed to other methods. |
A matrix of posterior probabilities of analogue-ness is returned. The
rows represent the fossil samples and the columns the groupings. There
are g+1
columns where g
is the number of groups. The
g+1
th column represents the Combined analysis which is the
overall posterior probability that a fossil sample is an analogue to a
training set sample (i.e. to any one of the groups).
