statistics - Prediction using sampleSelection package in R -


i use

require(sampleselection)

package in r. nicely regressing wish, however, prediction using coefficients confusing. tried

predict(heckitmodel, newdata)

in order create predictions normal linear model, seems uses coefficients of "outcome" part, not of probit part, estimate binary side of question.

would possible avoid manual handling of coefficients create predictions model? in other words, there automated way predict sampleselection selection object?

if there is, highly appreciate sample prediction, since cannot figure out while now.

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 <...
