Print and summary method functions for dose-response models represented in objects of class "`dosresmeta`

".

1 2 3 4 5 6 7 8 |

`x` |
an object of class |

`digits` |
an integer specifying the number of digits to which printed results must be rounded. |

`...` |
further arguments passed to or from other methods. |

`object` |
an object of class |

`ci.level` |
the confidence level used for defining the confidence intervals for the estimates of the (fixed-effects) coefficients. |

the `print`

method for class `dosresmeta`

only returns basic information of the fitted model, namely the call,
estimated (fixed-effects) coefficients, dimensions, and fit statistics (log-likelihood, AIC, BIC).

The `summary`

method function computes additional statistics and tests, and produces a list object of class `summary.dosresmeta`

.
The `print`

method function for this class, depending on the number of studies included in the analysis, shows additional information,
such as tables reporting the estimates for the fixed and random-effects parts of the model, Chi-square test for model significance,
Cochran Q test for heterogeneity and I-square.

The `summary`

method function for `dosresmeta`

objects produces a list of class "`summary.dosresmeta`

".
The components of the lists are some of those stored in the related `dosresmeta`

object, plus the following:

`AIC` | the value of the Akaike information criterion for the fitted `dosresmeta` model, obtained through a call to `AIC` . |

`BIC` | the value of the Bayesian information criterion for the fitted `dosresmeta` model, obtained through a call to `BIC` |

`corFixed` | the p x p correlation matrix of the fixed-effects coefficients,
obtained from the (co)variance matrix `vcov` |

`corRandom` | the p x p correlation matrix of the random effects, obtained from the between-study (co)variance matrix Ψ |

`qstat` | results from the Cochran Q test for heterogeneity. |

`ci.level` | the confidence level used for defining the confidence intervals for the estimates of the fixed-effects coefficients. |

`chisq` | overall test similar to anova. |

As usual, the `print`

method functions for classes "`dosresmeta`

" and "`summary.dosresmeta`

" do not return any value.

## Load data and run the model
data("alcohol_cvd")
model <- dosresmeta(formula = logrr ~ dose + I(dose^2), type = type, id = id,
se = se, cases = cases, n = n, data = alcohol_cvd)
## Defult print
model
## Specify digits
print(model, digit = 2)
## summary with 90th confidence intervals
summary(model, ci.level = .8)
