Usage

modmed7(
  rxm,
  rxw,
  rxxw,
  rxy,
  rwm,
  rwxw,
  rwy = 0,

  n = NULL
)

Value

Power for Model 7 Conditional Processes

Arguments

rxm

Correlation between predictor (x) and mediator (m)

rxw

Correlation between predictor (x) and moderator (w)

rxxw

Correlation between predictor (x) and interaction term (xw) - defaults to 0

rxy

Correlation between DV (y) and predictor (x)

rwm

Correlation between moderator (w) and mediator (m)

rwxw

Correlation between moderator (w) and interaction (xw) - defaults to 0

rwy

Correlation between DV (y) and moderator (w)

rmxw

Correlation between mediator (m) and interaction (xw) - Key value

rmy

Correlation between DV (y) and mediator (m)

rxwy

Correlation between DV (y) and interaction (xw) - defaults to 0

alpha

Type I error (default is .05)

rep

Number of samples drawn (defaults to 5000)

n

Sample size
