- The statistics argument in bootnet can now be "all"
- Added bootThreshold function to threshold a network based on bootstraps (e.g., bootstrapped interval includes 0)
- Added bootInclude function to obtain a network of bootstrap inclusion probabilities
- the 'statistics' argument in bootnet now defaults to c("edge","strength","outStrength","inStrength"). This means that closeness and betweenness are no longer stored by default!

- Included the 'includeDiagonal' argument to bootnet to include storing diagonal entries (self-loops) for directed networks only
- Bootnet now copies the library used by the user to the clusters when using nCores > 1. This is important for checkpoint and packrat compatability
- corStability now returns NA for incomputable correlations (e.g., due to infinite values)
o Experimental:
- Added default set "piecewiseIsing" for estimating Ising models while selecting participants on a sum-score (very experimental)
- Added default set "SVAR_lavaan" for step-up structural VAR model selection using Lavaan (experimental)
Changes in Version 1.1

- "graphicalVAR" - LASSO regularized graphical VAR models
- Some changes to mgm default:
- mgm version >= 1.2 is now required
- Renamed lev to level
- Renamed degree to order, now defaults to 2 instead of 3
- Added binarySign argument. Now chosen by defult.
- Added the 'replicationSimulator' function, which can be used to assess expected replicability of networks
- Many default sets now support the 'principalDirection' argument, which can be used to multiply variables with the sign of the first principal component

- Updated the 'genGGM' function to support various different network structures, with thanks to Mark Brandt!
- Added RSPBC and Hybrid centrality, thanks to Alex Christensen
- Added the 'alpha' argument to default set "pcor"

Changes in Version 1.0.0:
- Implemented the netSimulator function that allows for researchers to investigate sample size requirements and input arguments to estimateNetwork
- Added genGGM, ggmGenerator, and IsingGenerator functions to be used in netSimulator

Changes in version 0.4:

- Default set "IsingLL" has been renamed to "IsingSampler"

from within bootnet

networks and their accuracy: a tutorial paper. arXiv preprint,
arXiv:1604.08462.

differences between edge-weights and centralities
