Percentiles

Percentile('Expression','Percentile'=0.5)

Arguments

'Expression'

Signal or expression for which to form the percentile

'Percentile'

Percentile

Description

This function returns the defined percentile of 'Expression'.

The p% percentile is the smallest value of a set of measured values which is greater than p% of the number of values measured.

A typical percentile is the 50 % percentile, the so-called median. The median divides the set of values measured into two equal halves: 50 % of all values measured are smaller than the median value, the remaining 50 % are greater than or equal to it. Further typical percentiles are 25 % and 75 % which, together with the median, enable the division of a set of values measured into four groups, the so-called quartiles. (< 25%, < 50%, < 75%, ≥ 75%).

The Percentile function determines the percentile value of the total number of measuring points of a signal. Enter the percentile as a decimal value, i.e.:

  • 50 % --> 'Percentile' = 0.5 (default value)

  • 75 % --> 'Percentile' = 0.75

  • 95.9 % --> 'Percentile' = 0,959

This function is, for example, particularly useful when assessing the quality of a product where a particular property must comply with a defined classification.
PercentileInTime

PercentileInTime('Expression','Interval','Percentile'=0.5)

Arguments

'Expression'

Signal or expression for which to form the percentile

'Interval'

Length of the interval over which to form the percentile

'Percentile'

Percentile

Description

This function returns the percentile of 'Expression' over each time interval of the length 'Interval'.
PercentileValid

PercentileValid('Expression','Valid','Percentile'=0.5)

Arguments

'Expression'

Signal or expression for which to form the percentile

'Valid'

Length of the interval over which to form the percentile

'Percentile'

Percentile

Description

This function returns the percentile of 'Expression' for every interval (time or length) for which a related control signal 'Valid' is TRUE.
PercentileInTime

PercentileInTime('Expression','Interval','Percentile'=0.5)

Arguments

'Expression'

Signal or expression for which to form the percentile

'Interval'

Length of the interval over which to form the percentile

'Percentile'

Percentile

Description

This function returns the percentile of 'Expression' over each time interval of the length 'Interval'.
MPercentile

MPercentile('Expression','Interval','Percentile'=0.5)

Arguments

'Expression'

Signal or expression for which to form the percentile

'Interval'

Length of the moving interval over which to form the percentile

'Percentile'

Percentile

Description

This function returns the moving percentile of 'Expression' over each interval of the length 'Interval'. You can use this function for time based signals ('Interval' in seconds) as well as for length based signals ('Interval' in meters).
