glmmulti_boot {finalfit}

Binomial logistic regression multivariable models with bootstrapped confidence intervals: finalfit model wrapper

Description

Using finalfit conventions, produces a multivariable binomial logistic regression models for a set of explanatory variables against a binary dependent.

Usage

glmmulti_boot(.data, dependent, explanatory, R = 1000)

Arguments

.data

Dataframe.

dependent

Character vector length 1: name of depdendent variable (must have 2 levels).

explanatory

Character vector of any length: name(s) of explanatory variables.

R

Number of draws.

Details

Uses glm with finalfit modelling conventions. boot::boot is used to draw bootstrapped confidence intervals on fixed effect model coefficients. Output can be passed to fit2df.

Value

A multivariable glm fitted model with bootstrapped confidence intervals. Output is of class glmboot.
