The design region is explored via random sampling, which allows for more flexibility than traditional variance dispersion graphs. A formula interface is leveraged to provide access to complex model formulae. Graphics can be constructed simultaneously for multiple experimental designs and/or multiple model formulae. Instead of using pointwise optimization to find the minimum and maximum scaled prediction variance curves, which can be inaccurate and time consuming, this package uses quantile regression as an alternative.</p>crantastic.orgtag:crantastic.org,2005:TimelineEvent/539902016-08-16T23:15:12Z2016-08-16T23:15:12Zcrantastic_production tagged vdg with ExperimentalDesign<a href="/users/146">crantastic_production</a> <span class="action">tagged</span> <a href="/packages/vdg">vdg</a> with <a href="/task_views/ExperimentalDesign">ExperimentalDesign</a>crantastic_productiontag:crantastic.org,2005:TimelineEvent/462862016-01-05T14:32:55Z2016-01-05T14:32:55Zvdg was upgraded to version 1.1.3<a href="/packages/vdg">vdg</a> was <span class="action">upgraded</span> to version <a href="/packages/vdg/versions/46057">1.1.3</a><br /><h3>Package description:</h3><p>Facilities for constructing variance dispersion graphs, fraction- of-design-space plots and similar graphics for exploring the properties of experimental designs.
