Statistics::MeanT Function

double MeanT(TVec *Data, double Alpha = 0.05);

Trimmed mean.

#	Name	Type	Description
1	Data	TVec *	Data. An exception is raised if Data vector is complex.
2	Alpha = 0.05	double	Defines the percent of value excluded from mean calculation. If Alpha parameter is omitted, the default value 0.05 is used (meaning highest 2.5% and lowest 2.5% of data will be excluded). Alpha paramater must lie on the interval [0,1) otherwise an exception is raised.

Returns: the mean of all Data vector elements, excluding highest and lowest 100*Alpha/2 percents of value.

    double MT = MeanT(a,0.5);
    // MT = 79.2
