Missing not at random (MNAR) (also known as nonignorable nonresponse) is data that is neither MAR nor MCAR (i.e. the value of the variable that's missing is related to the reason it's missing). [5] To extend the previous example, this would occur if men failed to fill in a depression survey because of their level of depression.
MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities.
The app allows for screen recording and taking screenshots, either for a single window, a selected portion of the screen, or the entire screen. Screenshot is initialized whenever the user presses the keyboard shortcuts ⌘ Cmd + ⇧ Shift + 3 , ⌘ Cmd + ⇧ Shift + 4 , ⌘ Cmd + ⇧ Shift + 5 , or ⌘ Cmd + ⇧ Shift + 6 .
Such a point-source can, for example, be a bright light behind a screen with a pin hole, a fluorescent or metallic microsphere, or simply a dot painted on a screen. Calculation of the optical transfer function via the point spread function is versatile as it can fully characterize optics with spatial varying and chromatic aberrations by ...
The reason for this is that the graphics are bypassing the normal screen and going to a high-speed graphics processor on the graphics card by using a method called hardware overlay. Generally, there is no way to extract a computed image back out of the graphics card, [ citation needed ] though software may exist for special cases or specific ...

GNU Octave is a scientific programming language for scientific computing and numerical computation.Octave helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB.
Screen capture may refer to: Screenshot , an image file which shows the content of a computer's screen at the moment of shot Screencast , also known as a video screen capture , a digital recording of computer screen output, often containing audio narration
