## About

[Method](/about/licenses.md)

Fits the neighboring models of a fitted structural equation model and assesses the model uncertainty of the fitted model based on BIC posterior probabilities (BPP), using the method presented in Wu, Cheung, and Leung (2020) <doi:10.1080/00273171.2019.1574546>. See Pesigan, Cheung, Wu, Chang, and Leung (2026) <doi:10.3758/s13428-025-02921-x> for an introduction to the package.

**Cite**

#### Package

Run in R for the authors' entry:

`citation("modelbpp")`

The package provides a citation file, so `citation()` returns the authors' own entry.

It points to 10.3758/s13428-025-02921-x.

## Downloads

[Method](/about/downloads.md)

- Downloads in the last 30 days: 283 (down 22.5% on the 30 days before, the worse direction. It is the sum of 3 channels: CRAN, r2u and autoCRAN.)

CRAN alone: rank among CRAN packages, last 30 days: 15,410 of 26,529.

| Channel | Downloads in the last 30 days | In the total | Rank in that channel | Change |
| --- | ---: | --- | --- | --- |
| CRAN | 275 | yes | 15,410 of 26,529 | down 18.9% on the 30 days before, the worse direction |
| r2u | 6 | yes | 8,522 of 30,526 | down 14.3% on the 30 days before, the worse direction |
| autoCRAN | 2 | yes | 22,388 of 29,212 | down 89.5% on the 30 days before, the worse direction |

Other windows: [Last 90 days](/cran/modelbpp.md?win=90d#downloads), [Last 365 days](/cran/modelbpp.md?win=365d#downloads), [All time](/cran/modelbpp.md?win=all#downloads).

To leave channels out of the total, name them in the address, joined by dots: `?off=r2u.autocran`.

#### Over time

Downloads over time, the last 12 whole months:

| Aug 2026 | 269 | 7 | 34 | 310 |
| Sep 2026 | 330 | no figure | 13 | 343 |

First day on record: CRAN 21 Sep 2023, r2u 24 Sep 2023, autoCRAN 2 Jul 2026.

Every channel here counts downloads, so the channels can be stacked and summed for one period. Each channel counts in its own way and covers a different span of years, so read a sum as a rough total, and read a rise where a channel begins as that channel starting, not as growth.

Weeks start on Monday. A first or last week or month that the channel does not cover in full is left out, so every point is a whole period.

Days with no record add nothing to their week or month. For a little-used package that is usually a day with no downloads, but it can also be a gap in collection.

**Release notes (0.4.0)**

**Miscellaneous**

- In `get_add()` and `get_drop()`, the representation will switch to `RAM` if `LISREL` fails. (0.3.0.1)
- If the option `modelbpp.do_fit` is set to `FALSE` or not set, a parameter table will not be fitted to get the model *df*, leading to faster search. If this options is set to `TRUE`, then the parameter table will be fitted as in 0.3.0.2 or older version. (0.3.0.2, 0.3.0.3)
- Disabled more options to make the search faster. (0.3.0.3)
- Depends on R 4.1.0 or later now. (0.3.0.2)
- Slightly improved the speed by using an internal variant of `lavaan::parameterTable()`. (0.3.0.4)
- Added the option to use an internal function instead of `lavaan::update()`. Disabled by default. Enable it by setting the option `modelbpp.use_pt_add_only` to `TRUE`. Only applicable for models without constraints. (0.3.0.4, 0.3.0.5)
- In `fit_many()`, removed the printing of expected CPU time because the estimate is not reliable. (0.3.0.6)
