#Type of statistics

Mtas can produce several type of statistics, e.g. for positions, tokens or spans.

In general, statistics of type basic will require less resources than statistics of type advanced, whereas statistics of type advanced will require less than these of type full. If multiple statistics are possible and required, the parameters can be seperated with a comma.

Parameter	Description	Type
n	number of documents	basic
sum	total	basic
mean	mean	basic
min	minimum	advanced
max	maximum	advanced
sumsq	sum of squares	advanced
sumoflogs	sum of logs	advanced
geometricmean	geometric mean	advanced
quadraticmean	quadratic mean	advanced
variance	variance	advanced
populationvariance	population variance	advanced
standarddeviation	standard deviation	advanced
skewness	skewness	full
median	median	full
kurtosis	kurtosis	full
all	all of the above	full

Examples

n,sum
mean,standarddeviation

When not obligatory, usually \"n,sum,mean\" will be the default.

Distribution

Besides these parameters, a distribution can requested with (optional) arguments, optionally combined with one or more of the parameters listed above.

Parameter	Type	Arguments	Description	Obligatory
distribution()	full	start	start value	no
		end	end value	no
		step	size of intervals	no
		number	number of intervals	no

Examples

distribution()
distribution(start=0,end=1,number=10)
mean,standarddeviation,median,distribution(start=0,end=1,number=10)
