Computes the mean, standard deviation, and variance of the values in a sequence.
The input sequence.
This input accepts a double-precision, floating-point number or a 1D array of double-precision, floating-point numbers.
Weighting mode that this node uses to compute the input sequence.
Name | Description |
---|---|
Sample | Calculates the sample standard deviation and variance. |
Population | Calculates the population standard deviation and variance. |
Default: Sample
Length of each set of data.
The node performs computation for each set of data. sample length must be greater than zero.
This input is available only if you wire a double-precision floating-point number to x.
Default: 100
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Mean, or average, of the values in the input sequence.
Standard deviation calculated from the values in the input sequence.
Calculated variance of the values in the input sequence.
Error information.
The node produces this output according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
The node calculates the output values using the following equations.
where $\mu $ is mean and n is the number of elements in x.
