logistic_regression: Logistic regression

Description

Conduct a logistic regression analysis

Usage

logistic_regression(
  data = NULL,
  formula = NULL,
  formula_1 = NULL,
  formula_2 = NULL,
  z_values_keep = FALSE,
  constant_row_clean = TRUE,
  odds_ratio_cols_combine = TRUE,
  round_b_and_se = 3,
  round_z = 3,
  round_p = 3,
  round_odds_ratio = 3,
  round_r_sq = 3,
  round_model_chi_sq = 3,
  pretty_round_p_value = TRUE,
  print_glm_default_summary = FALSE,
  print_summary_dt_list = TRUE,
  print_model_comparison = TRUE,
  output_type = "summary_dt_list"
)

Value

the output will be a summary of logistic regression results, unless set otherwise by the output_type argument to the function.

Arguments

data

a data object (a data frame or a data.table)

formula

formula for estimating a single logistic regression model

formula_1

formula for estimating logistic regression model 1 of 2

formula_2

formula for estimating logistic regression model 2 of 2

z_values_keep

logical. Should the z values be kept in the table? (default = FALSE)

constant_row_clean

logical. Should the row for the constant be cleared except for b and standard error of b? (default = TRUE)

odds_ratio_cols_combine

logical. Should the odds ratio columns be combined? (default = TRUE)

round_b_and_se

number of decimal places to which to round b and standard error of b (default = 3)

round_z

number of decimal places to which to round z values (default = 3)

round_p

number of decimal places to which to round p-values (default = 3)

round_odds_ratio

number of decimal places to which to round odds ratios (default = 3)

round_r_sq

number of decimal places to which to round R-squared values (default = 3)

round_model_chi_sq

number of decimal places to which to round model chi-squared values (default = 3)

pretty_round_p_value

logical. Should the p-values be rounded in a pretty format (i.e., lower threshold: "<.001"). By default, pretty_round_p_value = TRUE.

print_glm_default_summary

logical. Should the default summary output of the glm objects be printed? (default = FALSE)

print_summary_dt_list

logical. Should the summaries of logistic regressions in a data table format be printed? (default = TRUE)

print_model_comparison

logical. Should the comparison of two logistic regression models be printed? (default = TRUE)

output_type

If output_type = "summary_dt_list" (default), the output of the function will be summaries of the two logistic regressions in a data.table format. If output_type = "glm_object_list", the output of the function will be the two glm objects estimating logistic regression models. If output_type = "glm_default_summary_list", the output of the function will be the R's default summary output for the two glm objects estimating logistic regression models. If output_type = "model_comparison_stats", the output of the function will be statistics from comparison of the two logistic regression models. If output_type = "all", the output of the function will be a list of the aforementioned outputs.

Examples

logistic_regression(data = mtcars, formula = am ~ mpg)
logistic_regression(
data = mtcars,
formula_1 = am ~ mpg,
formula_2 = am ~ mpg + wt)
