I can not return the predictions vector, Android Studio is not accepting. (incompatible Types) 

public double MediaMovelSimples(double[] valores) {

    int i;
    int j;

    double[] previsoes = new double[valores.length - 3];

    int parametro = 0;

    for (i = 0; i < valores.length - 3; i++) {

        for (j = parametro; j < parametro + 3; j++) {

            previsoes[i] += valores[j];
        }
        parametro+=1;
    }
    return previsoes;
}

  • What error appears? ask the question

  • incompatible Types

  • How do you want to return a vector of double if your method signature returns only one double?

the problem is that you are creating a method of type double and is returning an array of double change 

public double MediaMovelSimples(double[] valores) {

for

public double[] MediaMovelSimples(double[] valores) {

  • I get it. Thank you!

  • If you’ve cleared your doubts please close the question

Here public double MediaMovelSimples(double[] valores) you declare and here double[] previsoes, the two statements have to be equal. That’s what the error is saying incompatible types.
