Print detailed results of Copas selection model


Print method for objects of class summary.copas.

This function prints the following information:

Range of gamma0 values used (see help(copas));

Range of gamma1 values used (see help(copas));

Largest SE of all studies in meta-analysis;

Range of probability publishing trial with largest SE;

The next table gives details relating to the summary of the contour plot. Specifically, it gives details from fitting a straight line to each treatment-contour in the contour plot. Column 1 (headed level) shows the treatment-contours; column 2 (nobs) shows the number of observations used by the contour plot command within the copas function to plot this contour line; column 3 (adj.r.square) shows the adjusted r-square from fitting a straight line to this contour; columns 4 & 5 show the slope and its standard error from fitting a straight line to this contour.

Next, the printout of summary.copas is shown.


## S3 method for class 'summary.copas'
  backtransf = x$backtransf,
  legend = TRUE,
  digits = gs("digits"), = gs(""),



An object of class summary.copas.


A logical indicating whether results should be back transformed in printouts and plots. If backtransf = TRUE (default), results are printed as odds ratios rather than log odds ratio, for example.


A logical indicating whether a legend should be printed.


Minimal number of significant digits, see print.default.

Minimal number of significant digits for standard deviations and standard errors, see print.default.


Additional arguments (ignored).
