A new minor version of the stagedtrees package is available on CRAN.

Numerous new functions are available, such as a confidence interval method, likelihood ratio test and chain event graph plotting using the igraph package.

NEWS

• plot.ceg new plotting functions using igraph plotting.
• new util function make_stages_col which help computing stages colors for sevt and ceg plotting.
• sample_from now returns a data.frame of factors.
• prob earns a new argument conditional_on, that makes easier to compute conditional probabilities.
• confint.sevt, implement a method for confidence intervals for the parameters of a model of class sevt.
• lr_test new function, implementing likelihood-ratio test.
• functions to search optimal staged trees among different orders: search_best and search_greedy.
• cid function that implements context intervention discrepancy
• more and better testing and documentation.
