Performs meta-analysis and meta-regression using standard and robust methods with confidence intervals based on the profile likelihood. Robust methods are based on alternative distributions for the random effect, either the t-distribution (Lee and Thompson, 2008
Changes in metaplus version 0.7-11
o fixed bug in parsing which caused crash in normal profiling
Changes in metaplus version 0.7-10
o fixed warning from deprecated use of arrays
Changes in metaplus version 0.7-9
o changed options for integration of t distribution models so hopefully Gauss-Hermite is never needed
o modified Hessian calculations to avoid possible bug
o added warning message about study second parameter
o updated vignette and added code
Changes in metaplus version 0.7-8
o updated citation to reflect publication in R Journal
o updated vignette
Changes in metaplus version 0.7-7
o improved fitting for mixture models
o changed ordering of study labels for outlier probability plot to match ordering of forest plot
o added digits to parameters passed through from plot to summary lines
Changes in metaplus version 0.7-6
o added profile improvement introduced in 0.7-5 for normal models
o added option to perform integration in the t-distribution models using adaptive Gauss-Hermite quadrature to improve accuracy with studies with small standard errors
o correctly name CDP studies
o documentation enhancements
Changes in metaplus version 0.7-5
o added data parameter to metaplus to indicate where data is, and changed all examples and documentation to use this
o added a print method for metaplus objects which prints summary
o documentation changes
o renamed outlier.probs to outlierProbs and test.outliers to testOutliers to align with standard R naming conventions
o added further improvements to handing of tau^2 close to zero
o if new maxima is found during profiling then update solution (in practice this usually means that the likelihood is almost flat and very messy)
o add check for multimodal profile likelhood and give warning
o return profile so that this can be further examined
Changes in metaplus version 0.7-4
o added even more imports
Changes in metaplus version 0.7-3
o fixed occasional problems when tau^2 is zero for all distributions
o if likelihood is mis-shapen and CI plot requested then give a warning rather than fail
o check for inadequate number of studies and stop, or warn if only just adequate
o add cehck for appropriate model when calculating outlier probabilities
o add additional imports in NAMESPACE to pass R CMMD check
Changes in metaplus version 0.7-2
o fixed bug with fitting t-distribution when tau^2 was zero
o update documentation
Changes in metaplus version 0.7-1
o fixed bug related to singularity of Hessian
o when better solution found when profiling then use this fitted model
Changes in metaplus version 0.7-0
o improved convergence by using Nelder-Mead if nlminb failed
o used modified bbmle to fix bugs - changes will eventually be incorporated into bbmle
Changes in metaplus version 0.6-1
o improve profiling of t-distribution models by using multiple starting values
o fix problem when vinv=0 correctly
o fix documentation errors
o include examples vignette
Changes in metaplus version 0.6-0
o initial release
