PCMAbCdEf {PCMBase} | R Documentation |
Quadratic polynomial parameters A, b, C, d, E, f for each node
Description
An S3 generic function that has to be implemented for every
model class. This function is called by PCMLik
.
Usage
PCMAbCdEf(
tree,
model,
SE = matrix(0, PCMNumTraits(model), PCMTreeNumTips(tree)),
metaI = PCMInfo(NULL, tree, model, verbose = verbose),
verbose = FALSE
)
Arguments
tree |
a phylo object with N tips. |
model |
an S3 object specifying both, the model type (class, e.g. "OU") as well as the concrete model parameter values at which the likelihood is to be calculated (see also Details). |
SE |
a k x N matrix specifying the standard error for each measurement in
X. Alternatively, a k x k x N cube specifying an upper triangular k x k
factor of the variance covariance matrix for the measurement error
for each tip
Note that the above behavior is consistent with the treatment of the model
parameters |
metaI |
a list returned from a call to |
verbose |
logical indicating if some debug-messages should printed. |
