plot_DSpower: 2D or 3D visualization for the Dunn-Sidak power

In wangjunyao0121/RASMART: Response Adaptive Sequencial Multiple Assignments Randomized Trial

Description

2D or 3D visualization for the Dunn-Sidak power

Usage

plot_DSpower(Q1, Q2, Q3, pi1, pi2, P, n, ...)

Arguments

Q1	a vector of numeric value for the range of Q12 probability
Q2	a vector of numeric value for the range of Q21 probability
Q3	a vector of numeric value for the range of Q31 probability
pi1	the respond rate of treatment 1, 2, 3 in stage I in SMART
pi2	the respond rate for patients who do not respond to a treatment in stage I, but respond to another treatment in stage II
P	Randomization probability in stage I
n	Sample size in SMART
...	other arguments fits to DSpower and plot3D

Details

One of Q1, Q2, Q3 must be a single value, and the other two should be a range of numerical value between 0 and 1.

Value

a 2D contour plot or 3D plot for the Dunn-Sidak power

Examples

Q1 = 0.3
Q2 = seq(0.1, 0.9, by = 0.005)
Q3 = seq(0.1, 0.9, by = 0.005)
pi1 = c(0.4, 0.35, 0.25)
pi2 = c(0.35, 0.32, 0.36, 0.56, 0.37, 0.4)
P = c(1/3, 1/3, 1/3)
n = 365

plot_DSpower(Q1, Q2, Q3, pi1, pi2, P, n, col = "black", nlevels = 30)
