plots.Full {BDEsize} | R Documentation |
This function produces graphs between the sample size, power and the detectable standardized effect size of full factorial design.
plots.Full(factor.lev, interaction = FALSE, delta_type = 1, delta = c(1, 0, 1),
deltao = NULL, alpha = 0.05, beta = 0.2, type = 1, maxsize = 1000)
factor.lev |
vector of the numbers of levels for each factor. |
interaction |
specifies whether two-way interaction effects are included in a model with the main effects. When |
delta_type |
specifies the type of standardized effect size: 1 for standard deviation type and 2 for range type. |
delta |
vector of effect sizes: |
deltao |
the minimal detectable standardized effect size for power vs the sample size plot when |
alpha |
Type I error. |
beta |
Type II error. |
type |
graph type: 1 for Power vs Delta plot, 2 for Delta vs Sample size plot, and 3 for Power vs Sample size plot. |
maxsize |
tolerance for sample size. |
This function produces graph between the sample size, power 1-beta
and the detectable standardized effect size delta
of full factorial design.
According to type
, it displays plot of Power vs Delta, Delta vs Sample size, or Power vs Sample size.
