experimental.stddev() function
experimental.stddev() is subject to change at any time.
experimental.stddev() returns the standard deviation of non-null values in the _value
column for each input table.
Standard deviation modes
The following modes are available when calculating the standard deviation of data.
sample
Calculate the sample standard deviation where the data is considered to be part of a larger population.
population
Calculate the population standard deviation where the data is considered a population of its own.
Function type signature
(<-tables: stream[{A with _value: float}], ?mode: string) => stream[{A with _value: float}]
For more information, see Function type signatures.
Parameters
mode
Standard deviation mode or type of standard deviation to calculate.
Default is sample.
Available options:
- sample
- population
tables
Input data. Default is piped-forward data (<-).
Examples
Return the standard deviation in input tables
import "experimental"
import "sampledata"
sampledata.float()
