একটি পরিস্থিতিটি কল্পনা করুন: আমাদের তিনটি মাইনের historicalতিহাসিক রেকর্ড রয়েছে (20 বছর)। রূপালী উপস্থিতি কি পরের বছরে সোনার সন্ধানের সম্ভাবনা বাড়িয়ে তোলে? কিভাবে এই ধরনের প্রশ্ন পরীক্ষা?
এখানে উদাহরণ ডেটা:
mine_A <- c("silver","rock","gold","gold","gold","gold","gold",
"rock","rock","rock","rock","silver","rock","rock",
"rock","rock","rock","silver","rock","rock")
mine_B <- c("rock","rock","rock","rock","silver","rock","rock",
"silver","gold","gold","gold","gold","gold","rock",
"silver","rock","rock","rock","rock","rock")
mine_C <- c("rock","rock","silver","rock","rock","rock","rock",
"rock","silver","rock","rock","rock","rock","silver",
"gold","gold","gold","gold","gold","gold")
time <- seq(from = 1, to = 20, by = 1)
