mvsum {reportRmd}

Get multivariate summary dataframe

Description

Returns a dataframe with the model summary and global p-value for multi-level variables.

Usage

mvsum(
  model,
  data,
  digits = getOption("reportRmd.digits", 2),
  showN = TRUE,
  showEvent = TRUE,
  markup = TRUE,
  sanitize = TRUE,
  nicenames = TRUE,
  CIwidth = 0.95,
  vif = TRUE
)

Arguments

model

fitted model object

data

dataframe containing data

digits

number of digits to round to

showN

boolean indicating sample sizes should be shown for each comparison, can be useful for interactions

showEvent

boolean indicating if number of events should be shown. Only available for logistic.

markup

boolean indicating if you want latex markup

sanitize

boolean indicating if you want to sanitize all strings to not break LaTeX

nicenames

boolean indicating if you want to replace . and _ in strings with a space.

CIwidth

width for confidence intervals, defaults to 0.95

vif

boolean indicating if the variance inflation factor should be included. See details

Details

Global p-values are likelihood ratio tests for lm, glm and polr models. For lme models an attempt is made to re-fit the model using ML and if,successful LRT is used to obtain a global p-value. For coxph models the model is re-run without robust variances with and without each variable and a LRT is presented. If unsuccessful a Wald p-value is returned. For GEE and CRR models Wald global p-values are returned.

If the variance inflation factor is requested (VIF=T) then a generalised VIF will be calculated in the same manner as the car package.

VIF for competing risk models is computed by fitting a linear model with a dependent variable comprised of the sum of the model independent variables and then calculating VIF from this linear model.
