Create random matrix
General
- Type: Matrix Upload
Brief description
Create a matrix of given dimensions containg random numbers drawn from a single or a superposition of several normal distributions.
Parameters
Number of rows
Specifies the number of rows the randomly created matrix should have (default: 100). Rows are called “Row 1”, Row 2“, etc.
Number of columns
Specifies the number of columns the randomly created matrix should have (default: 10). Columns are called “Column 1”, “Column 2”, etc.
Percentage of missing values
Specifies the percentage of missing values the created matrix should contain (default: 0).
Mode
Defines how many normal distributions should be included in the matrix (default: One normal distribution). The number of normal distributions can be specified from a predefined list:
- One normal distribution (parameter window A)
- Two normal distributions (parameter window B)
- Many normal distributions (parameter window C)
Distance
This parameter is just relevant, if the parameter “Mode” is set to “Two normal distributions”. It defines the distance between the two generated normal distributions (default: 2).
How many
This parameter is just relevant, if the parameter “Mode” is set to “Many normal distributions”. It defines how many normal distributions should be in the generated matrix (default: 3).
Box size
This parameter is just relevant, if the parameter “Mode” is set to “Many normal distributions”. It specifies the edge length of the hyper cubes in which the centers of the normal distributions are placed at random (default: 2).
