pyarrow.compute.stddev#
- pyarrow.compute.stddev(array,/,*,ddof=0,skip_nulls=True,min_count=0,options=None,memory_pool=None)#
Calculate the standard deviation of a numeric array.
The number of degrees of freedom can be controlled using VarianceOptions.By default (ddof = 0), the population standard deviation is calculated.Nulls are ignored. If there are not enough non-null values in the arrayto satisfyddof, null is returned.
- Parameters:
- arrayArray-like
Argument to compute function.
- ddof
int, default 0 Number of degrees of freedom.
- skip_nullsbool, default
True Whether to skip (ignore) nulls in the input.If False, any null in the input forces the output to null.
- min_count
int, default 0 Minimum number of non-null values in the input. If the numberof non-null values is belowmin_count, the output is null.
- options
pyarrow.compute.VarianceOptions, optional Alternative way of passing options.
- memory_pool
pyarrow.MemoryPool, optional If not passed, will allocate memory from the default memory pool.
