Dalam statistik, normalisasi kuantil<\/a> adalah metode yang membuat dua distribusi menjadi identik dalam hal sifat statistik.<\/span><\/p>\n

Contoh berikut menunjukkan cara melakukan normalisasi kuantil di R.<\/span><\/p>\n

Contoh: normalisasi kuantil di R<\/strong><\/span><\/h3>\n

Misalkan kita membuat bingkai data berikut di R yang berisi dua kolom:<\/span><\/p>\n

 #make this example reproducible\n<\/span>set. seeds<\/span> (0)\n\n#create data frame with two columns\n<\/span>df <- data. frame<\/span> (x=rnorm(1000),\n                 y=rnorm(1000))\n\n#view first six rows of data frame\n<\/span>head(df)\n\n           xy\n1 1.2629543 -0.28685156\n2 -0.3262334 1.84110689\n3 1.3297993 -0.15676431\n4 1.2724293 -1.38980264\n5 0.4146414 -1.47310399\n6 -1.5399500 -0.06951893<\/strong><\/pre>\n
 #calculate quantiles for x and y\n<\/span>sapply(df, function(x) quantile(x, probs = seq(0, 1, 1\/4)))\n\n               xy\n0% -3.23638573 -3.04536393\n25% -0.70845589 -0.73331907\n50% -0.05887078 -0.03181533\n75% 0.68763873 0.71755969\n100% 3.26641452 3.03903341\n<\/strong><\/pre>\n
 Perhatikan bahwa x dan y memiliki nilai kuantil yang serupa, tetapi nilainya tidak identik.<\/span><\/p>\n
 Misalnya nilai persentil ke-25 untuk x adalah -0,708<\/strong> dan nilai persentil ke-25 untuk y adalah -0,7333<\/strong> .<\/span><\/p>\n
 Untuk melakukan normalisasi kuantil, kita dapat menggunakan fungsi normalize.quantiles()<\/strong> dari paket preprocessCore<\/a> di R:<\/span><\/p>\n
 library<\/span> (preprocessCore)\n\n#perform quantile normalization\n<\/span>df_norm <- as. data<\/span> . frame<\/span> ( normalize.quantiles<\/span> ( as.matrix<\/span> (df)))\n\n#rename data frame columns\n<\/span>names(df_norm) <- c(' x<\/span> ', ' y<\/span> ')\n\n#view first six row of new data frame\n<\/span>head(df_norm)\n\n           xy\n1 1.2632137 -0.28520228\n2 -0.3469744 1.82440519\n3 1.3465807 -0.16471644\n4 1.2692599 -1.34472394\n5 0.4161133 -1.43717759\n6 -1.6269731 -0.07906793\n<\/strong><\/pre>\n
 Kita kemudian dapat menggunakan kode berikut untuk menghitung kuantil untuk x dan y lagi:<\/span><\/p>\n
 #calculate quantiles for x and y\n<\/span>sapply(df_norm, function(x) quantile(x, probs = seq(0, 1, 1\/4)))\n\n               xy\n0% -3.14087483 -3.14087483\n25% -0.72088748 -0.72088748\n50% -0.04534305 -0.04534305\n75% 0.70259921 0.70259921\n100% 3.15272396 3.15272396\n<\/strong><\/pre>\n
 Perhatikan bahwa kuantilnya sekarang sama untuk x dan y.<\/span><\/p>\n
 Kita dapat mengatakan bahwa x dan y telah dinormalisasi kuantil. Dengan kata lain, kedua distribusi tersebut sekarang identik dalam hal sifat statistik.<\/span><\/p>\n
