Я хочу настроить модерируемую модерируемую модель посредничества с пакетами lavaan
и processR
. Модель следующая:
![enter image description here](https://i.stack.imgur.com/0V0GR.png)
Я пытался создать следующие модерации:
Innovativeness:Age
и
PBC:Innovativeness:Age
Мои данные (df
):
df <- structure(list(Attitude = structure(c(33, 30, 37, 29, 36, 42,
27, 35, 35, 27, 22, 25, 42, 25, 38, 35, 38, 36, 34, 40), label = "Attitude", format.spss = "F8.2"),
SubNorm = structure(c(46, 53, 30, 27, 55, 37, 14, 55, 55,
57, 37.4, 48, 68, 43, 55, 39, 51.7, 36, 51.7, 60), label = "Subjective Norm", format.spss = "F8.2"),
PBC = structure(c(50, 50, 45, 38, 48, 41, 34, 40, 47, 42,
22, 38, 56, 42, 48, 38, 33, 30, 46, 45), label = "Perceived Behavior Control", format.spss = "F8.2"),
Intent = structure(c(21, 17, 14, 15, 15, 21, 18, 18, 19,
15, 10, 12, 21, 10, 19, 15, 21, 21, 19, 21), label = "Intention", format.spss = "F8.2"),
Behavior = structure(c(59, 36, 44, 35, 62, 60, 38, 38, 68,
42, 35, 16, 77, 24, 73, 35, 64, 35, 69, 60), label = "Behavior", format.spss = "F8.2"),
Religiosity = c(28L, 28L, 24L, 30L, 19L, 25L, 23L, 21L, 20L,
15L, 21L, 20L, 21L, 17L, 27L, 29L, 24L, 23L, 17L, 25L), Education = c(45L,
55L, 46L, 28L, 52L, 48L, 48L, 55L, 53L, 30L, 60L, 31L, 31L,
33L, 46L, 58L, 53L, 55L, 38L, 27L), Innovativeness = c(38L,
39L, 37L, 54L, 40L, 49L, 30L, 53L, 58L, 45L, 59L, 32L, 43L,
49L, 57L, 59L, 37L, 54L, 52L, 43L), Age = c(46L, 35L, 27L,
33L, 42L, 56L, 49L, 42L, 41L, 31L, 31L, 43L, 45L, 59L, 44L,
57L, 28L, 48L, 28L, 55L)), row.names = c(NA, -20L), class = c("tbl_df",
"tbl", "data.frame"))
Я пробовал это:
library(lavaan)
library(processR)
md_1 <- tripleEquation(
labels = list(X = "PBC", M = "Intent", Y = "Behavior"),
covar = list(name = c("SubNorm", "Attitude"),
site = c("M", "M")),
moderator = list(name = c('Innovativeness', 'Age', 'Religiosity'),
site = list('a', 'a2', 'b'))
)
a2
- поток новаторства (W) - см. Изображение статистической диаграммы.
Анализ:
fit_1 <- sem(
model = md_1,
estimator = 'ML',
data = df,
se = 'bootstrap',
bootstrap = 10,
fixed.x = TRUE
)
Но:

Потоки Innovativeness:Age
и PBC:Innovativeness:Age
не были произведены.
Как настроить эту строку:
moderator = list(name = c('Innovativeness', 'Age', 'Religiosity'),
site = list('a', 'a2', 'b'))
, чтобы получить эти желаемые потоки?
Спасибо.
