In contrast, the in-depth interview is sensitive to the subtleties of life events and should be the preferred method when data of any precision and accuracy are required in an empirical study.D. M. Gorman PhDState University of New JerseyBehavioral Medicine...
The equals method is used to check whether two objects are same or not. It needs to be overridden if we want to check the objects based on property.For example, Employee is a class that has 3 data members: id, name and salary. But, we want to check the equality of employee object ...
"Currently, statistical agencies pin the entire trade value of a product to the last place it was exported from, even though the parts in the product come from many other countries. This method of data collection is based on the International Monetary Fund's Balance of Payments Manual, which ...
15. Explain the KNN imputation method, in brief. KNN is the method that requires the selection of several nearest neighbors and a distance metric at the same time. It can predict both discrete and continuous attributes of a dataset. A distance function is used here to find the similarity ...
Some of the changes are: Java Stream API for collection classes for supporting sequential as well as parallel processing Iterable interface is extended with forEach() default method that we can use to iterate over a collection. It is very helpful when used with lambda expressions because its ...
publicinterfaceCollectionextendsIterable{//method definitions} The framework also consists ofMapinterface, which is part of the collection framework but does not extend theCollectioninterface. 3. WhyCollectiondoes not extend Cloneable and Serializable interface?
It involves the systematic method of applying data modeling techniques. Database Design: This is the process of designing the database. The database design creates an output which is a detailed data model of the database. Strictly speaking, database design includes the detailed logical model of...
Method 1: On File Basis In this method, the replication factor is changed on the basis of file using Hadoop FS shell. The command used for this is: $hadoop fs – setrep –w2/my/test_file Here, test_file is the filename that’s replication factor will be set to 2. ...
Create a standalone function bind that is functionally equivalent to the method Function.prototype.bind. How can you avoid callback hells? What is the purpose of callback function as an argument of setState? Which is the preferred option between callback refs and findDOMNode()? What is a ...
Quicksort operates inO(N*logN)time. This is generally true of the divide-and-conquer algorithms, in which a recursive method divides a range of items into two groups and then calls itself to handle each group. In this situation the logarithm actually has a base of2: The running time is ...
