nameTarget variable name
name1First target variable name
name2Second target variable name
useSelWhen TRUE, the statistics are derived from the only active samples

◆ getCorrelation()

double Db::getCorrelation ( const String name1,
const String name2,
bool  useSel = false 
) const

Returns the correlation coefficient between two target variables

◆ getMaximum()

double Db::getMaximum ( const String name,
bool  useSel = false 
) const

Returns the maximum of the target variable

◆ getMean()

double Db::getMean ( const String name,
bool  useSel = false 
) const

Returns the mean of the target variable

◆ getMinimum()

double Db::getMinimum ( const String name,
bool  useSel = false 
) const

Returns the minimum of the target variable

◆ getRange()

VectorDouble Db::getRange ( const String name,
bool  useSel = false 
) const

Returns a vector containing the minimum and maximum of the target variable

◆ getStdv()

double Db::getStdv ( const String name,
bool  useSel = false 
) const

Returns the standard deviation (square root of the variance) of the target variable

◆ getVariance()

double Db::getVariance ( const String name,
bool  useSel = false 
) const

Returns the variance of the target variable
