oph_aggregate_stats_final¶

Description¶

Behaviour

It computes statistical indexes based on mask value working vertically on the columns of arrays of partial results obtained from a merge of fragments, on which oph_aggregate_stats_partial has been applied.

Parameters

input measure type: Ophidia typing. Supported types are: ‘oph_double’; ‘oph_float’; ‘oph_long’; ‘oph_int’; ‘oph_short’; ‘oph_byte’.
output measure type: Ophidia typing. Supported types are: ‘oph_double’; ‘oph_float’; ‘oph_long’; ‘oph_int’; ‘oph_short’; ‘oph_byte’.
measure: input partial results.
mask: 7-bit mask
- 0000000: invalid
- 1xxxxxx: mean
- x1xxxxx: variance
- xx1xxxx: std dev
- xxx1xxx: skew
- xxxx1xx: excess kurtosis
- xxxxx1x: max
- xxxxxx1: min
- 1111111: all (default)
- 101: mean + std dev
- ...

Return type

Binary-array.

Examples

Compute mean, maximum and minimum of a set of time series from partial results.

oph_aggregate_stats_final('OPH_DOUBLE','OPH_DOUBLE',measure,'1000011')

Operation type

Aggregate.
