REndo 2.4.32021-09-03

BUG FIXES

  • In method multilevelIV matrices could not be constructed if all groups were of the same size. Thanks to pinson06 for reporting.

REndo 2.4.22021-02-10

BUG FIXES

  • In the copulaCorrection method with a single endogenous regressor the correlation coefficient rho was wrongly constraint to [0, 1] instead of to [-1, 1]. Further, rho was not included in parts of the calculations. Special thanks to Fredrik Falkenström for reporting this observation!

REndo 2.4.12020-10-14

SIGNIFICANT USER-VISIBLE CHANGES

  • Allow using the method copulaCorrection with a single endogenous regressor

REndo 2.4.02020-05-24

SIGNIFICANT USER-VISIBLE CHANGES

  • Add a formal assumption test for method hetErrorsIV to detect weak instruments

NEW FEATURES

  • The log-likelihood function underlying copulaCorrection case 1 is refactored and implemented using Rcpp and RcppEigen what makes it considerably faster
  • Improved checks of user input that disallow any non-finite values in the data
  • New data was generated for dataHetIV

REndo 2.3.12020-02-17

  • None. Version bump in order to resubmit to CRAN after package was archived.

REndo 2.3.02019-08-05

SIGNIFICANT USER-VISIBLE CHANGES

  • Add support for predictions through method predict for every model

BUG FIXES

  • Fix wrong calculations for the fitted values and residuals in the enhanced OLS cases of copulaCorrection
  • Improved documentation

REndo 2.2.12019-06-05

SIGNIFICANT USER-VISIBLE CHANGES

  • To tweak the lmer model fit in multilevelIV to their linking, users can supply a parameter lmer.control

NEW FEATURES

  • Warning in confint if there are NAs in the bootstrapped estimates for copulaCorrection
  • Updated vignette

BUG FIXES

  • The coefficient estimates for multilevelIV are more consistent and independent of data sorting due to different standard settings for fitting lmer
  • Bootstrapped parameter estimates for copualCorrection result in fewer NAs when using L-BFGS-B as optimization method

REndo 2.2.02019-04-13

SIGNIFICANT USER-VISIBLE CHANGES

  • The augmented OLS method in copulaCorrection also bootstraps parameter estimates
  • The summary output for results from copulaCorrection was adapted to reflect that standard errors are bootstrapped
  • Removed support for the S3 method labels because of inconsistent behavior across methods

NEW FEATURES

  • Bootstrapping for copulaCorrection case 1 is now considerably faster
  • New data was generated for dataMultilevelIV

BUG FIXES

  • The sigma matrix in latentIV is constructed as in the paper by Ebbes et al. what improves results. Special thanks to Jordan Henderson for investigating and pointing this out!
  • In latentIV, the parameter for group membership (theta5) is now transformed back and reported correctly.
  • The vcov matrix for latentIV is corrected for the transformation in theta5.
  • The bootstrapping in copulaCorrection case 1 now creates samples of the same length as the original data
  • The (percentile) confidence intervals and vcov for results from copulaCorrection now rely on bootstraping

REndo 2.1.02019-01-16

SIGNIFICANT USER-VISIBLE CHANGES

  • The reworked method multilevelIV and accompanying data was added back to the package
  • Vignette REndo-introduction was added to showcase package usage
  • Users can supply a parameter optimx.args to tweak the LL optimization to their liking

NEW FEATURES

  • Method confint was added for methods latentIV and copulaCorrection
  • Examples and documentation were improved for all methods
  • New data was generated for dataHetIV
  • The default number of iterations for all optimizations was increased to 100’000

BUG FIXES

  • To avoid infrequent warnings, the parameter sigma used in copulaCorrection was constrained to > 0
  • Various spelling mistakes were fixed

REndo 2.0.02018-11-10
