APAKAH MAKSUD EXPECTED VALUE dalam CORSICA?
Nilai yang dijangkakan
Dalam teori kebarangkalian, nilai yang dijangkakan merujuk, secara intuitif, kepada nilai pemboleh ubah rawak yang satu akan "mengharapkan" untuk mencari jika seseorang boleh mengulangi proses pemboleh ubah rawak suatu bilangan tak terhingga kali dan mengambil purata nilai-nilai yang diperolehi. Secara lebih formal, nilai yang diharapkan adalah purata wajaran bagi semua nilai yang mungkin. Dalam erti kata lain, setiap nilai yang mungkin boleh diubah oleh pemboleh ubah rawak didarabkan dengan berat yang ditugaskannya, dan hasil yang dihasilkan kemudian ditambah bersama untuk mencari nilai yang diharapkan. Berat yang digunakan untuk mengira purata ini adalah kebarangkalian dalam hal pemboleh ubah rawak diskret, atau nilai-nilai fungsi kepadatan kebarangkalian dalam hal pemboleh ubah rawak yang berterusan. Dari sudut pandangan teori yang ketat, nilai jangkaan pembolehubah berterusan adalah integral daripada pemboleh ubah rawak berkenaan dengan ukuran kebarangkaliannya. Oleh kerana kebarangkalian tidak boleh negatif, nilai yang diharapkan adalah berkadar dengan kawasan di bawah lengkung graf nilai-nilai pemboleh ubah rawak yang didarabkan dengan kebarangkalian nilai itu. Oleh itu, bagi pemboleh ubah rawak yang berterusan nilai yang dijangkakan ialah had jumlah tertimbang, iaitu yang penting.
Definisi expected value dalam kamus Corsica
Takrif nilai yang dijangkakan dalam kamus adalah jumlah atau taksiran semua nilai yang mungkin bagi pemboleh ubah rawak, atau sebarang fungsi yang diberikan, didarabkan oleh kebarangkalian masing-masing nilai pembolehubah. Simbol: E. E ialah purata pengagihan; E = E c di mana c adalah pemalar Juga dipanggil: jangkaan matematik.
