2.
Uji Smirnov-Kolmogorov menggunakan nilai Delta Kritik = 0,19400, |
|
|
|
menghasilkan distribusi yang terbaik
adalah LOG PEARSON III |
|
|
|
karena maksimum delta yang terjadi =
0,12936, sedangkan |
|
|
|
3.
Uji Chi Kuadrat menggunakan nilai Chi Kritik = 11,07000, |
|
|
|
menghasilkan distribusi yang terbaik
adalah GUMBEL |
|
|
|
karena maksimum Chi kuadrat yang terjadi
= 10,66667 |
|
|
|
4. Seluruh formulasi
berdasarkan buku Applied Hydrology oleh V.T. Chow et. al |
|
|
|
5.
Untuk data BUKAN ekstrim tahunan, analisis keandalan di atas cocok |
|
|
|
untuk analisis KEBUTUHAN air. |
