diagnostic.bcmeta | R Documentation |
This function performers an approximated Bayesian cross-validation for a bcmeta object and specially designed diagnostics to detect the existence of a biased component.
## S3 method for class 'bcmeta' diagnostic( object, post.p.value.cut = 0.05, study.names = NULL, size.forest = 0.4, lwd.forest = 0.2, shape.forest = 23, bias.plot = TRUE, cross.val.plot = TRUE, level = c(0.5, 0.75, 0.95), x.lim = c(0, 1), y.lim = c(0, 10), x.lab = "P(Bias)", y.lab = "Mean Bias", title.plot = paste("Bias Diagnostics Contours (50%, 75% and 95%)"), kde2d.n = 25, marginals = TRUE, bin.hist = 30, color.line = "black", color.hist = "white", color.data.points = "black", alpha.data.points = 0.1, S = 5000, ... )
