## set working directory to the directory containing this script
print("generate synthetic data sets")
source("varselection.generatedata.run.R")
print("generate long MCMC chain")
source("varselection.mcmc.run.R")
## The rest requires running batch scripts.
## The tables were obtained by running varselection.script.R using GNU parallel.
## The script takes 8 arguments:
# JOB_ID
# NRUNS
# design # 0 for independent design, 1 for correlated
# n # number of rows
# p # number of columns
# SNR # Signal to noise ratio, e.g. 0.5, 1, or 2
# k # set to zero if only interested in meeting times
# m # set to zero if only interested in meeting times
# for instance to run the script on 10 machines, 10 times on each machine,
# with either design=0 and design=1, with n=500, with p=1000 and p=5000, and with k=m=0
# parallel -j10 'Rscript varselection.script.R {}' ::: {1..10} ::: 10 ::: {0,1} ::: 500 ::: {1000,5000} ::: {0.5,1,2} ::: 0 ::: 0
## Once this has been run with the desired values of n and p
print("producing tables")
source("varselection.tables.R")
## The figures were obtained as follows.
## For the impact of dimension
print("producing results on the impact of dimension")
source("varselection.differentp.R")
source("varselection.differentp.plots.R")
## For the impact of the hyperparameter kappa
## First, the script "varselection.clusterscript.kappas.R" was run on a cluster.
## This was done by creating a script, say "run.odyssey.varselection.kappas.sh", which contains the following lines
# #!/bin/bash
# #SBATCH -J varselection_rep # Job name
# #SBATCH -n 1 # Number of cores
# #SBATCH -N 1 # All cores on one machine
# #SBATCH -t 0-24:00 # Runtime in D-HH:MM
# #SBATCH -p shared # Partition to submit to (general, shared, serial_requeue)
# #SBATCH --mem-per-cpu=2000M # Memory pool for all cores (see also --mem-per-cpu)
# #SBATCH --mail-type=END # Type of email notification- BEGIN,END,FAIL,ALL
# #SBATCH --mail-user=username@provider.com # Email
# #SBATCH --array=1-600 # Requesting 100 jobs
#
# ## LOAD SOFTWARE ENV ##
# source new-modules.sh
# module load R/3.4.2-fasrc01
# export R_LIBS_USER=$HOME/apps/R:$R_LIBS_USER
# input=varselection.differentkapps.R #****** modify this line
# cd /n/home12/pjacob/ #****** modify this line
#
# srun R CMD BATCH --no-save $input out/$input.$SLURM_ARRAY_TASK_ID.out #****** modify this line
## and then running in a command line
## sbatch run.odyssey.varselection.kappas.sh
## Once these are produced, it remains to run long MCMC chains for comparison,
## and to produce the plots. This is done as follows.
print("producing results on the impact of hyperparameter kappa")
source("varselection.differentkappas.R")
source("varselection.differentkappas.plots.R")
