pstest: Performs the power analysis for the projected score test
In carolynlou/pstestr: Performs power analysis for the projected score test

This is an independent function which calls setup from sim_setup(), which sets up all of the variables needed for one value of kperc, percentage of independent variables with nonzero signal and one value of mbeta, mean coefficient for non zero effects uniform around that value That function loops through the variables k and beta.

pstest(nsim = 500, seed = 2019, mbeta = 0, kperc = 40, n = 100,
  p = 1000, model = "normal", sigma = 1, alpha = 0.05,
  betasp = TRUE, rs = c(10, 20, 50), mc.cores = 1, Gprime, GQs, GQs2,
  R1nams, R2nams, nams, H1, A, G, linkatlambda, simresults, powresults)
