Summary of Class "lefkoMat"
Description
A function to simplify the viewing of basic information describing the
matrices produced through functions flefko3()
,
flefko2()
, rlefko3()
, rlefko2()
,
aflefko2()
, rleslie()
, and
fleslie()
.
Usage
## S3 method for class 'lefkoMat'
summary(object, colsums = TRUE, ...)
Arguments
object |
An object of class |
colsums |
A logical value indicating whether column sums should be shown for U matrices, allowing users to check stage survival probabilities. Defaults to TRUE. |
... |
Other parameters. |
Value
A summary of the object, showing the number of each type of matrix, the number of annual matrices, the number of estimated (non-zero) elements across all matrices and per matrix, the number of unique transitions in the dataset, the number of individuals, and summaries of the column sums of the survival-transition matrices. This function will also yield warnings if any survival-transition matrices include elements outside of the interval [0,1], if any fecundity matrices contain negative elements, and if any matrices include NA values.
Notes
Under the Gaussian and gamma size distributions, the number of estimated
parameters may differ between the two ipm_method
settings. Because
the midpoint method has a tendency to incorporate upward bias in the
estimation of size transition probabilities, it is more likely to yield non-
zero values when the true probability is extremely close to 0. This will
result in the summary.lefkoMat
function yielding higher numbers of
estimated parameters than the ipm_method = "CDF"
yields in some cases.
