When modelsearch()
is called, it first trims the dataset down to just
the variables that will be used, and just data for complete cases in those
variables. It then builds global models for all vital rates and runs them. If
a global model fails, then the function proceeds by dropping any two-way
interactions and trying again. If this fails, then the function will continue
to attempt dropping terms, first patch, then year, then individual
covariates, then combinatons of the above, and finally individual identity.
If these attempts fail and the approach used is mixed
, then the
function will try running a glm version of the original failed model, and use
that as a global model if it runs properly. Finally, if all attempts fail,
then the function returns a 1
to allow model building assuming a
constant rate or probability.
Setting suite = "cons"
prevents the inclusion of size and reproductive
status as fixed, independent factors in modeling. However, it does not
prevent any other terms from being included. Density, age, individual
covariates, individual identity, patch, and year may all be included.
The mechanics governing model building are fairly robust to errors and
exceptions. The function attempts to build global models, and simplifies
models automatically should model building fail. Model building proceeds
through the functions lm()
(GLM with Gaussian response),
glm()
(GLM with Poisson, Gamma, or binomial response),
glm.nb()
(GLM with negative binomial response),
zeroinfl()
(GLM with zero-inflated Poisson or negative
binomial response), vglm()
(GLM with zero-truncated
Poisson or negative binomial response), lmer()
(mixed
model with Gaussian response), glmer()
(mixed model with
binomial, Poisson, or Gamma response), and glmmTMB()
(mixed model with negative binomial, or zero-truncated or zero-inflated
Poisson or negative binomial response). See documentation related to these
functions for further information. Any response term that is invariable in
the dataset will lead to a best-fit model for that response represented by a
single constant value.
Exhaustive model building and selection proceeds via the
dredge()
function in package MuMIn
. This function
is verbose, so that any errors and warnings developed during model building,
model analysis, and model selection can be found and dealt with.
Interpretations of errors during global model analysis may be found in
documentation for the functions and packages mentioned. Package MuMIn
is used for model dredging (see dredge()), and errors and
warnings during dredging can be interpreted using the documentation for that
package. Errors occurring during dredging lead to the adoption of the global
model as the best-fit, and the user should view all logged errors and
warnings to determine the best way to proceed. The quiet = TRUE
and
quiet = "partial"
options can be used to silence dredge warnings, but
users should note that automated model selection can be viewed as a black
box, and so care should be taken to ensure that the models run make
biological sense, and that model quality is prioritized.
Exhaustive model selection through dredging works best with larger datasets
and fewer tested parameters. Setting suite = "full"
may initiate a
dredge that takes a dramatically long time, particularly if the model is
historical, individual covariates are used, or a zero-inflated distribution
is assumed. In such cases, the number of models built and tested will run at
least in the millions. Small datasets will also increase the error associated
with these tests, leading to adoption of simpler models overall. Note also
that zero-inflated models are processed as two models, and so include twice
the assumed number of parameters. If suite = "full"
, then this
function will switch to a main effects global model for the zero-inflated
parameter models if the total number of parameters to test rises above the
limits imposed by the dredge()
function in package
MuMIn
.
Accuracy of vital rate models is calculated differently depending on vital
rate and assumed distribution. For all vital rates assuming a binomial
distribution, including survival, observation status, reproductive status,
and juvenile version of these, accuracy is calculated as the percent of
predicted responses equal to actual responses. In all other models, accuracy
is actually assessed as a simple R-squared in which the observed response
values per data subset are compared to the predicted response values
according to each best-fit model. Note that some situations in which factor
variables are used may result in failure to assess accuracy. In these cases,
function modelsearch()
simply yields NA
values.
Care must be taken to build models that test the impacts of state in occasion
t-1 for historical models, and that do not test these impacts for
ahistorical models. Ahistorical matrix modeling particularly will yield
biased transition estimates if historical terms from models are ignored. This
can be dealt with at the start of modeling by setting
historical = FALSE
for the ahistorical case, and
historical = TRUE
for the historical case.
This function handles generalized linear models (GLMs) under zero-inflated
distributions using the zeroinfl()
function, and zero-
truncated distributions using the vglm()
function. Model
dredging may fail with these functions, leading to the global model being
accepted as the best-fit model. However, model dredges of mixed models work
for all distributions. We encourage the use of mixed models in all cases.
The negative binomial and truncated negative binomial distributions use the quadratic structure emphasized in Hardin and Hilbe (2018, 4th Edition of Generalized Linear Models and Extensions). The truncated negative binomial distribution may fail to predict size probabilities correctly when dispersion is near that expected of the Poisson distribution. To prevent this problem, we have integrated a cap on the overdispersion parameter. However, when using this distribution, please check the matrix column sums to make sure that they do not predict survival greater than 1.0. If they do, then please use either the negative binomial distribution or the zero-truncated Poisson distribution.
If density dependence is explored through function modelsearch()
,
then the interpretation of density is not the full population size but rather
the spatial density term included in the dataset.
Users building vital rate models for Leslie matrices must set
vitalrates = c("surv", "fec")
or vitalrates = "leslie"
rather
than the default, because only survival and fecundity should be estimated in
these cases. Also, the suite
setting can be set to either age
or cons
, as the results will be exactly the same.
Users wishing to test age, density, group, or individual covariates, must
include test.age = TRUE
, test.density = TRUE
,
test.group = TRUE
, or test.indcova = TRUE
(or
test.indcovb = TRUE
or test.indcovc = TRUE
, whichever is most
appropriate), respectively, in addition to stipulating the name of the
variable within the dataset. The default for these options is always
FALSE
.
