oph_operator¶

Description¶

Behaviour

It applies an operator on the whole measure array.

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 measure.
operator name: type of operator
- ‘oph_count’: computes the number of actual values (not missing);
- ‘oph_max’: computes the maximum (default);
- ‘oph_min’: computes the minimum;
- ‘oph_avg’: computes the mean of all elements;
- ‘oph_sum’: computes the sum of all elements;
- ‘oph_std’: computes the standard deviation;
- “oph_cmoment”: computes the central moment;
- “oph_acmoment”: computes the absolute central moment;
- “oph_rmoment”: computes the raw moment;
- “oph_armoment”: computes the absolute raw moment;
- “oph_quantile”: computes the quantile.
hierarchy: it defines a hierarchy [not used].
order: order used in evaluation the moments or value of the quantile in range [0, 1].
missingvalue : value to be considered as missing value; by default it is NAN (for “oph_double” and “oph_float”).

Return type

Binary-array.

Examples Compute the mean of all elements.
