| \title{Anova Tables} |
| \usage{ |
| anova(object, \dots) |
| } |
| \description{ |
| Compute analysis of variance (or deviance) tables for one or more |
| fitted model objects. |
| } |
| \arguments{ |
| \item{object}{an object containing the results returned by a model |
| fitting function (e.g., \code{lm} or \code{glm}).} |
| \item{\dots}{additional objects of the same type.} |
| } |
| \value{ |
| This (generic) function returns an object of class \code{anova}. |
| These objects represent analysis-of-variance and analysis-of-deviance tables. |
| When given a single argument it produces a table which |
| tests whether the model terms are significant. |
| |
| When given a sequence of objects, \code{anova} tests |
| the models against one another in the order specified. |
| |
| The print method for \code{anova} objects prints tables in a |
| \sQuote{pretty} form. |
| } |
| \section{Warning}{ |
| The comparison between two or more models will only be valid if they |
| are fitted to the same dataset. This may be a problem if there are |
| missing values and \R's default of \code{na.action = na.omit} is used. |
