umx_scale_reliabilities: Accumulate scale reliabilities and report them as a table

In umx: Structural Equation Modeling and Twin Modeling in R

Accumulate scale reliabilities and report them as a table

Description

umx_score_scale() with alpha = TRUE prints reliability coefficients. umx_scale_reliabilities() collects these across scales, then reports them together.

Usage

umx_scale_reliabilities(
  action = "show",
  scale_name = NULL,
  reliability = NULL,
  type = NULL,
  report = c("markdown", "html"),
  digits = 2
)

Arguments

action	One of "init" (start or clear the store), "add" (append one row), or "show" (print and return the table). "print" is accepted as an alias of "show". Default "show".
scale_name	Name of the scale (single string, required when action = "add").
reliability	Reliability value (single numeric, required when action = "add").
type	Type of reliability. When action = "add", a single string (required), e.g. "alpha", "omega_t", or "omega_h". When action = "show", an optional filter: one or more types to report (NULL, the default, reports all rows).
report	Format for the printed table: "markdown" or "html".
digits	Decimal places for the printed table (default 2). Display only: stored values keep full precision.

Details

To use, call with "init", score your scales, then call with "show".

Value

• invisible data.frame with columns scale, reliability, and type

umx_scale_reliabilities("add", scale_name = "Agreeableness", reliability = 0.72, type = "alpha")
umx_scale_reliabilities("add", scale_name = "Agreeableness", reliability = 0.75, type = "omega_t")
umx_scale_reliabilities("show")
umx_scale_reliabilities("show", type = "alpha") # just the alphas
umx_scale_reliabilities("init") # clear the store
