simple_slopes_analysis: Simple slopes analysis

Description

Conduct a simple slopes analysis, typically to probe a two-way interaction.

Usage

simple_slopes_analysis(
  data = NULL,
  iv_name = NULL,
  dv_name = NULL,
  mod_name = NULL,
  round_b = 2,
  round_se = 2,
  round_t = 2,
  round_p = 3,
  focal_values = NULL
)

Arguments

data

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

iv_name

name of the independent variable (IV)

dv_name

name of the dependent variable (DV)

mod_name

name of the moderator variable (MOD)

round_b

number of decimal places to which to round coefficients from the regression analysis (default = 2)

round_se

number of decimal places to which to round standard error values from the regression analysis (default = 2)

round_t

number of decimal places to which to round t statistics from the regression analysis (default = 2)

round_p

number of decimal places to which to round p values from the regression analysis (default = 2)

focal_values

this input will be used only in cases where IV is continuous. In such cases, what are the focal values of the IV at which to estimate the effect of MOD on DV? By default, values corresponding to the mean of IV +/-1 SD will be used.
