eatATA 1.1.1

CRAN release: 2022-11-28

• internal testing fix

eatATA 1.1.0

CRAN release: 2022-09-26

• getMean2PLN() and getMean2PLN() for calculating the mean of the two- and three-parameter log-normal response time distributions, based on a set of parameters.
• getMar2PLN() and getVar2PLN() for calculating the variance of the two- and three-parameter log-normal response time distributions, based on a set of parameters
• bug fix in inspectSolution() (works with tibbles now)

• bug fix in itemTuples() (#1)

eatATA 1.0.0

CRAN release: 2021-07-06

• updated overview vignette
• added mathematical formulations of implementation on the help page of itemValuesConstraint()
• added acrossFormsConstraint() for constraints across test forms
• more rigorous input checks for all constraint functions

eatATA 0.11.2

CRAN release: 2021-05-02

• fix occasional system dependent test failure

eatATA 0.11.1

CRAN release: 2021-04-16

• fix non ascii character in help file

eatATA 0.11.0

• constraint functions re-named consistently (now ending all on Constraint)
• objective function functions re-named consistently (now ending all on Objective)
• itemUsageConstraint() argument whichItem now takes a character vector (item identifiers) as input
• itemInclusionConstraint() added to force items to be in the same test forms
• stemInclusionTuples() added to create inclusion tuples from column with shared stimulus
• itemExclusionTuples() renamed to itemTuples(), as it can also be used for itemInclusionConstraint()
• argument names in itemTuples() and itemExclusionConstraint() slightly modified
• added simulated item pools for examples
• renamed all item pools consistently (items_mini, items_diao, items_pilot, items_vera, items_lsa)

eatATA 0.10.0

CRAN release: 2021-02-10

• argument nItems either completely removed from constraint functions or exchangeable with itemIDs
• itemTargetConstraint() substituted by minimaxConstraint(), maximinConstraint(), maxConstraint(), minConstraint(), cappedMaximinConstraint() which allow for different types of optimization goals
• Symphony added as available solver (via Rsymphony)
• inspectSolution() now allows character variables in the input if sums are calculated
• autoItemValuesMinMax() now works for different test length via testLength argument

Documentation

• reworked use case vignette
• added minimal example vignette
• added vignette with package overview

Internal Changes

• input checks (feasible solution?) for analyzeBlockExclusion() and analyzeComplexBlockExclusion()
• uniqueness of argument itemID is checked
• introduction of constraint-class with specific methods and constructor functions

eatATA 0.9.1

• GLPK and lpSolve solvers are now supported
• useSolver() function implemented, which calls solver APIs directly
• inspectSolution() and appendSolution() functions, which use useSovler() output
• prepareConstraints() and processGurobiOutput() retired
• calculateIIF() calculates item information function
• calculateExpectedRT() calculates expected response times

eatATA 0.7.0
