Ini adalah distribusinya:
Karena data jelas tidak terdistribusi normal, banyak uji statistik tidak dapat diterapkan pada data ini. Tapi mungkin saya bisa mengubah data menjadi distribusi normal?
Bagaimana saya bisa mengetahui distribusi mana ini?
Dan bagaimana saya bisa mentransfer data ke distribusi normal?
Tujuannya adalah untuk melakukan analisis varians (MANOVA) atau semacamnya (data yang disajikan di sini adalah dua variabel dependen).

. Dan tidak - tidak ada yang dikecualikan.Setiap distribusi kontinu dapat diubah menjadi distribusi normal melalui proses yang disebut Gaussianization (Chen & Gopinath, 2001) . Untuk distribusi univariat, Gaussianization sederhana. Jika variabel acakY memiliki fungsi distribusi kumulatif (CDF) FY dan Φ adalah CDF dari standar normal, lalu
akan memiliki distribusi normal standar. Ini mudah dilihat, karena CDF dariX adalah
JikaY didistribusikan secara eksponensial dengan kurs λ , maka data dapat ditransformasikan melalui
yang terlihat mirip dengan logaritma:
Saya tidak menggunakan R , tapi saya yakin Anda dapat menemukan implementasi CDF terbalik (juga dikenal sebagai fungsi kuantil ) dari normal,Φ−1 .

y = 3x
, tapi saya tidak mengertiF(x) = 3x
. Saya memiliki ini di sekolah selama bertahun-tahun, dan mendengarnya di universitas setiap hari, tetapi "fungsi x" sama sekali tidak berarti bagi saya. Saya tidak melihat apa hubungannya dengan dunia di mana saya hidup dan mengalami melalui indra saya. Karena itu saya tidak mengerti apa yang Anda katakan mungkin saya lakukan di "data dapat diubah melalui ...". Namun +1 untuk kebaikan Anda dalam mencoba membantu saya. Bukan salahmu aku tidak bisa berpikir secara abstrak.Bagaimana saya bisa mengetahui distribusi mana ini? Di sini Anda dapat menggunakan beberapa uji statistik dari paket R fitdistrplus. Dari paket Anda akan menemukan crateria pas yaitu AIC, BIC dll. Pemasangan distribusi 'gamma atau distribusi mor seperti "normal". Inilah metodenya.
Kemudian akhirnya Anda akan menemukan di antara beberapa model teoritis yang terbaik yang menyerupai data yang Anda amati.
Dan bagaimana saya bisa mentransfer data ke distribusi normal? Di sini Anda dapat menggunakan Box Cox Transfom
Inilah exmaple kerja saya:
