coef.dosresmeta function

Extract Coefficients and (Co)Variance Matrix from dosresmeta Objects

These method functions return the estimated fixed-effects coefficients and their (co)variance matrix for fitted dose-response meta-analytical models represented in objects of class "dosresmeta".

## S3 method for class 'dosresmeta'
coef(object, format = c("vector", "matrix"), ...)

## S3 method for class 'dosresmeta'
vcov(object, ...)

Arguments

• object: an object of class "dosresmeta".
• format: format of the returned object.
• ...: further arguments passed to or from other methods.

Returns

For coef, a vector (default) or matrix with the estimated (fixed-effects) coefficients. For vcov, the (co)variance matrix of the estimated (fixed-effects) coefficients.

Examples

## 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) 

## Fixed-effect coefficients
coef(model)

## Fixed-effect (co)variance matrix
vcov(model)
