Dummy Package in R -


could ?

i using dummy package in r (function dummy) convert categorical variable(10 categories) dummy variables because of algorithms using (adaboost , rotation forest), don't handle categorical variables well.

after using package 10 dummy variables factors. expected them numeric 1s , 0s.

should convert them numeric ? or use them factors.

thanks lot !!!! best pedro

after performing 1 hot encoding there no difference keeping them factor or numeric . better not perform 1 hot encoding tree based models.it decrease performance.here article describing effect of 1 hotted variables..it better pass categorical variables converting them factors

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
