DATA REDUCTION USING R
Reduksi data merupakan teknik transformasi sekumpulan variabel menjadi lebih sedikit, membentuk beberapa kelompok variabel, atau mengelompokkan data. Tujuan reduksi data sangat beragam yakni, mulai menangani high dimensional data, membuat indeks, melihat positioning beberapa objek berdasarkan beberapa variabel. Reduksi data sangat bermanfaat dalam menguak informasi dari data yanng ada pada berbagai industri.
Pada course ini kita akan melakukan reduksi data menggunakan software R Studio mulai dari level yang paling dasar. R Studio merupakan salah satu software statistik dan data science yang memiliki berbagai macam keunggulan di dalamnya. Pertama, R Studio berlisensi gratis sehingga Anda bebas menggunakannya sampai kapanpun secara legal. Kedua, memiliki banyak paket (package) pengolahan data dan selalu update sehingga Anda dapat menemukan hampir semua metode analisis apapun mulai dari yang terdahulu sampai yang terbaru dan termasuk yang berhubungan dengan reduksi data . Ketiga, visualisasi grafik yang sangat canggih dan tidak kalah dari software lainnya. Saat ini R studio banyak diterapkan pada berbagai sektor Industri terutama untuk hal-hal yang membutuhkan analisis data.
