lmtp 1.4.0

New Features

• Can now estimate the effects of simultaneous interventions on multiple variables.
• New pre-packaged shift function, ipsi() for estimating IPSI effects using the risk ratio.
• lmtp_control() now replaces extra estimator arguments.

Bug Fixes

• Standard errors now incorporate survey weights (see issue #134).
• Bug fix when shift is NULL and data is a tibble (see issue #137)

General

• The intervention_type argument has been fully deprecated.
• Now attempting to detect intervention type errors (see issue #98).

lmtp 1.3.3

New Features

Bug Fixes

• Fixed a bug where estimators return incorrect parameter estimates for a specific DGP (see issue #130)

General

lmtp 1.3.2

New Features

Bug Fixes

• Fixed bug in calculation of EIF where density ratios were not non-cumulative product ratios. Previous variance estimates starting with version 1.0 were incorrect. Point-estimates remain unaffected.

General

• Updating citations

lmtp 1.3.1

New Features

• Added parameter .return_full_fits. Allows the user to decide if full SuperLearner fit should be returned (issue #119).
• intervention_type argument replaced with mtp.

Bug Fixes

• Added a check for fits$id being NULL. Fixes a backwards compatibility bug (issue #117).
• data.table version must be 1.13.0 or later. This was when the function fcase was released (issue #122).

General

• Changed ‘effect’ to ‘estimate’ in ‘Population mean effects’ portion of output (issue #120).

lmtp 1.3.0

New Features

Bug Fixes

General

• Major internal refactor. Argument checking is now performed using checkmate package.
• .SL_folds argument split into .learners_outcome_folds and .learners_trt_folds.

lmtp 1.1.0

New Features

Bug Fixes

• Corrected standard errors when providing id with lmtp_contrast (issue #110).

General

• Removed the requirement that folds must be greater than 1 (issue #112).

lmtp 1.0.0

New Features

• New shifted parameter for directly passing shifted data instead of using a shift function (issue #89).
• New intervention_type parameter required for specifying if the intervention of interest is a static regime, a dynamic regime, or a modified treatment policy (issue #94).
• return_all_ratios removed as an argument. Returned density ratios are now non-cumulative product ratios.

Bug Fixes

• Density ratio trimming now occurs in the same spot for all estimators and is only performed on non-cumulative product ratios (issue #\93).
• Fixed issue where lmtp_tmle and lmtp_sdr weren’t using validation set density ratios.
• No longer fails when data is a data.table (issue #88).

General

• Removing extra column in sim_point_surv data set (issue #91).
• Paper citation updated with release in JASA (issue #103).

lmtp 0.9.1

Bug Fixes

• Fixed a bug that caused failure when knitting the getting-started.Rmd vignette when using new version of the future package (issue #100).

General

• GitHub links added to DESCRIPTION (issue # 99).

Bug Fixes

• Fixed a bug that caused failure when no variation existed in the outcome at a type point (issue #92).
• No longer fails when data is a data.table (issue #88).

General

• Removing extra column in sim_point_surv data set (issue #91).

lmtp 0.9.0

New Features

• New weights parameter for observation sampling weights (issue #78).

• For time-to-event analysis, survival probability is now estimated instead of the cumulative incidence. This fixes a bug with IPW and survival problems.

• Outcome type now accepts "survival" for explicit indication of a survival outcome (issue #76). Because of this lmtp_ipw() now requires setting the outcome type.

• New .trimming parameter for trimming extreme density ratios.

• New .SL_folds parameter that controls the splits used for fitting the SuperLearner (issue #84).

• New .return_all_ratios parameter that allows for returning non-cumulative product density ratios to the user.

• bound parameter renamed to .bound.

Bug Fixes

• Fixed a bug that caused the final estimate to be incorrectly estimated with SDR (issue #87).

• Fixed a bug that outputted outcome regressions and density ratios in incorrect order compared to the original data.

• Fixed a bug in the missing data check that threw an error for missing data after an observation experiences the outcome.

• Fixed a bug in the calculation of standard errors when the id parameter is specified.

• Fixed a bug that resulted in NA censoring indicators throwing an error for missing data.

• Fixed a bug about values() being deprecated in the future package (issue #82).

• Fixed a warning from the future package regarding random number generation (issue #81).

• Fixed create_node_list() returns description (issue #77).

Dependencies

• slider dependency removed.

• data.table added as a dependency.

General

• event_locf() speed greatly improved (issue #80).

• Migrated continuous integration from Travis-CI to GitHub Actions.

• Added a NEWS.md file to track changes to the package.

• License change to GPL-3.
