Changes in 1.0-0 * New vignette: vignette("BasicsIdentifiabilityPower", package = "mpt"), basic use cases, identifiability checks, power analysis * agememory (new data set): age differences in episodic memory (Bayen, 1990) * pwrsim (new data sets): results from simulation-based power analyses Changes in 0.8-0 * mptspec: accept .replicates for user-provided model specifications; handle equation names more flexibly * update.mptspec: recognize .replicates argument * mpt: accept 1d tables as data; always return treeid as factor * *.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 * mptspec: return treeid so mpt() can use it 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 * mpt.Rd (value): update * mptEM.Rd (usage, value): update Changes in 0.1-0 * initial release on CRAN
