Find and change name of element of array inside other class

Hey,

I wanna write down custom inspector which will change a name of my array which holds statistics.

    [System.Serializable]
    public class Statistics
    {
        float[] baseValues = new float[6];
        float[] modValues = new float[6];
}

This is the class which is included in Person class, and I wanted to know how to get inside of the class from custom editor of Person class.

            _personStats = serializedObject.FindProperty("personStats");

This line gives me the class, but how can I change the array elements names of the arrays inside of it?

I will appreciate any help,
Thanks!

int index = 0;
float myValue = 1;

_personStats.FindPropertyRelative(“baseValues”).GetArrayElementAt(index).floatValue = myValue;
