Summary of Regression Models as HTML Table

## Install package "strengejacke" from GitHub (`devtools::install_github("strengejacke/strengejacke")`) to load all sj-packages at once!

tab_model() is the pendant to plot_model(), however, instead of creating plots, tab_model() creates HTML-tables that will be displayed either in your IDE’s viewer-pane, in a web browser or in a knitr-markdown-document (like this vignette).

HTML is the only output-format, you can’t (directly) create a LaTex or PDF output from tab_model() and related table-functions. However, it is possible to easily export the tables into Microsoft Word or Libre Office Writer.

This vignette shows how to create table from regression models with tab_model(). There’s a dedicated vignette that demonstrate how to change the table layout and appearance with CSS.

Note! Due to the custom CSS, the layout of the table inside a knitr-document differs from the output in the viewer-pane and web browser!

# sample data

efc <- as_factor(efc, c161sex, c172code)

A simple HTML table from regression results

First, we fit two linear models to demonstrate the tab_model()-function.

m1 <- lm(barthtot ~ c160age + c12hour + c161sex + c172code, data = efc)
m2 <- lm(neg_c_7 ~ c160age + c12hour + c161sex + e17age, data = efc)

The simplest way of producing the table output is by passing the fitted model as parameter. By default, estimates, confidence intervals (CI) and p-values (p) are reported. As summary, the numbers of observations as well as the R-squared values are shown.

Automatic labelling

As the sjPlot-packages features labelled data, the coefficients in the table are already labelled in this example. The name of the dependent variable(s) is used as main column header for each model. For non-labelled data, the coefficient names are shown.

data(mtcars)
m.mtcars <- lm(mpg ~ cyl + hp + wt, data = mtcars)
tab_model(m.mtcars)

  drug = as.factor(sample(c("nonsense", "useful", "placebo"), 100, TRUE)),

Generalized linear models

For generalized linear models, the ouput is slightly adapted. Instead of Estimates, the column is named Odds Ratios, Incidence Rate Ratios etc., depending on the model. The coefficients are in this case automatically converted (exponentiated). Furthermore, pseudo R-squared statistics are shown in the summary.

m3 <- glm(
  tot_sc_e ~ c160age + c12hour + c161sex + c172code, 
  data = efc,
  family = poisson(link = "log")
)

efc$neg_c_7d <- ifelse(efc$neg_c_7 < median(efc$neg_c_7, na.rm = TRUE), 0, 1)
m4 <- glm(
  neg_c_7d ~ c161sex + barthtot + c172code,

Show or hide further columns

tab_model() has some argument that allow to show or hide specific columns from the output:

show.est to show/hide the column with model estimates.
show.ci to show/hide the column with confidence intervals.
show.se to show/hide the column with standard errors.
show.std to show/hide the column with standardized estimates (and their standard errors).
show.p to show/hide the column with p-values.
show.stat to show/hide the column with the coefficients’ test statistics.
show.df for linear mixed models, when p-values are based on degrees of freedom with Kenward-Rogers approximation, these degrees of freedom are shown.

Adding columns

In the following example, standard errors, standardized coefficients and test statistics are also shown.

tab_model(m1, show.se = TRUE, show.std = TRUE, show.stat = TRUE)

Removing columns

In the following example, default columns are removed.

barthtot		0.97
Observations	840	815
R² Nagelkerke	0.106	0.191

Removing and sorting columns

Another way to remove columns, which also allows to reorder the columns, is the col.order-argument. This is a character vector, where each element indicates a column in the output. The value "est", for instance, indicates the estimates, while "std.est" is the column for standardized estimates and so on.

By default, col.order contains all possible columns. All columns that should shown (see previous tables, for example using show.se = TRUE to show standard errors, or show.st = TRUE to show standardized estimates) are then printed by default. Colums that are excluded from col.order are not shown, no matter if the show*-arguments are TRUE or FALSE. So if show.se = TRUE, butcol.order does not contain the element "se", standard errors are not shown. On the other hand, if show.est = FALSE, but col.order does include the element "est", the columns with estimates are not shown.

In summary, col.order can be used to exclude columns from the table and to change the order of colums.

tab_model(
  m1, show.se = TRUE, show.std = TRUE, show.stat = TRUE,
  col.order = c("p", "stat", "est", "std.se", "se", "std.est")
)

Collapsing columns

With collapse.ci and collapse.se, the columns for confidence intervals and standard errors can be collapsed into one column together with the estimates. Sometimes this table layout is required.

Defining own labels

There are different options to change the labels of the column headers or coefficients, e.g. with:

pred.labels to change the names of the coefficients in the Predictors column. Note that the length of pred.labels must exactly match the amount of predictors in the Predictor column.
dv.labels to change the names of the model columns, which are labelled with the variable labels / names from the dependent variables.
Further more, there are various string.*-arguments, to change the name of column headings.

tab_model(
  m1, m2, 
  pred.labels = c("Intercept", "Age (Carer)", "Hours per Week", "Gender (Carer)",
                  "Education: middle (Carer)", "Education: high (Carer)", 
                  "Age (Older Person)"),

  string.pred = "Coeffcient",
  string.ci = "Conf. Int (95%)",
  string.p = "P-Value"

Another option would be scientific notation, using p.style = "scientific", which also can be combined with digits.p.

tab_model(m1, m2, p.style = "scientific", digits.p = 2)

Automatic matching for named vectors

Another way to easily assign labels are named vectors. In this case, it doesn’t matter if pred.labels has more labels than coefficients in the model(s), or in which order the labels are passed to tab_model(). The only requirement is that the labels’ names equal the coefficients names as they appear in the summary()-output.

# example, coefficients are "c161sex2" or "c172code3"
summary(m1)
#> 
#> Call:
#> lm(formula = barthtot ~ c160age + c12hour + c161sex + c172code,

Keep or remove coefficients from the table

Using the terms- or rm.terms-argument allows us to explicitly show or remove specific coefficients from the table output.

tab_model(m1, terms = c("c160age", "c12hour"))

	Total score BARTHEL INDEX
Predictors	Estimates	CI	p
carer’ age	-0.21	-0.35 – -0.07	0.004
average number of hours of care per week	-0.28	-0.32 – -0.24	<0.001
Observations	821
R² / R² adjusted	0.271 / 0.266

Note that the names of terms to keep or remove should match the coefficients names. For categorical predictors, one example would be:

tab_model(m1, rm.terms = c("c172code2", "c161sex2"))
