equation names more flexibly

* *.Rd: update references
Changes in 0.7-0
* mptspec("proCNI"): return specification of proCNI model of moral dilemma
judgment (Hennig & Huetter, 2020)
* moraldilemma (new data sets): moral dilemma judgment data (Hennig &
Huetter, 2020) and replication data for Experiment 2b
* citysize: add replication data for Hilbig et al. (2010, Experiment 7)
* selectiontask: add replication data for Klauer et al. (2007, Experiment 1)
Changes in 0.6-2
* recogROC: add replication data for Broeder and Schuetz (2009,
Experiment 3)
* Small adjustments for R >= 4.0.0 features
Changes in 0.6-1
* mpt: handle treeid's more flexibly

Changes in 0.6-0
* mptspec("WST"): return specification of inference-guessing model (Klauer,
Stahl, & Erdfelder, 2007) for the Wason selection task (prompted by
Charlotte Tanis)
* selectiontask (new data set): Wason selection task data (Klauer et al.,
2007)
* prospecMemory: add replication data for Smith and Bayen (2004,
Experiment 1)
* DESCRIPTION: new URL
Changes in 0.5-4
* citysize (new data set): city-size paired-comparison task
* recogROC.R, recogROC.Rd: first column contains percentage of target (old),
not new, items (reported by Katharina Naumann)
* *.Rd: add DOIs to all references
* NAMESPACE: properly import from graphics
Changes in 0.5-3
* anova.mpt: now works with stats::print.anova()
* mpt: small improvements for mpt(..., method = "EM")
Changes in 0.5-2
* BUG FIX: mpt(..., method = "EM") could fail when a symbol in the model was
also used as an object name in the work space
* mpt: newline and other space characters in model specifications are now
also allowed for the EM fitting method (not only for BFGS)
* logLik.mpt: add multinomial constant
* NAMESPACE: import graphics, utils
Changes in 0.5-1
* mpt: the start argument expects starting values between zero and one
regardless of the fitting method
* mptspec("prospec"): return specification of event-based prospective memory
model (Smith & Bayen, 2004)
* prospecMemory, recogROC (new data sets): prospective memory data (Smith &
Bayen, 2004), recognition memory data (Broeder & Schuetz, 2009)
Changes in 0.5-0
* User-visible changes: MPT models are now specified via the new mptspec()
function. Its return value serves as an input to mpt() which fits the
model to data. It allows for more flexible parameter restrictions than the
earlier mechanism. It includes all the default MPT models (plus new ones)
that were formerly returned by the (now defunct) mptmodel() function. See
?mptspec and ?mpt for details.
* coef.mpt, vcov.mpt, confint.mpt: new logical argument logit to switch
between logit-scale and probability-scale representation
* mpt: new argument method = c("BFGS", "EM") to select the fitting method
* vcov.mpt: new argument what = c("vcov", "fisher") to return either the
covariance matrix or the Fisher information
* predict.mpt (new function): predicted response frequencies or
probabilities for a given MPT model and optionally new data
* valence (new data set): word valence and source memory for vertical
position
Changes in 0.4-1
* BUG FIX: typo in vcov.mpt(), hence wrong standard errors (reported by
Rainer Alexandrowicz and Bartosz Gula)
* recogROC (new data set): recognition memory data (Broeder & Schuetz, 2009)
* nobs.mpt (new function): extracts number of nonredundant response
categories
* Add citation file: useR! 2011 talk
Changes in 0.4-0
* simulate.mpt (new function): simulate responses from a fitted mpt model
* mptmodel (new function): return formulae for some prevalent MPT models
* mpt.R: mpt() function now takes dataframe or vector input
* NAMESPACE: new file
Changes in 0.3-0
* BUG FIX: two frequencies in the proact data set were incorrect
* vcov.mpt (new function): covariance matrix of mpt model parameters
* summary.mpt (new function): summary method for mpt objects
* mpt.Rd (examples): update
* proact.Rd (examples): update
Changes in 0.2-0
* BUG FIX: df in logLik.mpt() was incorrect by one
* residuals.mpt (new function): residuals for MPT models
* plot.mpt (new function): plots MPT residuals against fitted values
* proact (new data set): recall frequencies for DaPolito's experiment on
proactive inhibition
* mptEM: new stepsize argument
