Method Detail

getNumberOfElements
int getNumberOfElements()
Get the number of elements (e.g. corpus size) for the distribution.- Returns:
- the number of elements
-
setNumberOfElements
@Deprecated void setNumberOfElements(int n)
Deprecated.as of v2.1Set the number of elements (e.g. corpus size) for the distribution. The parameter value must be positive; otherwise anIllegalArgumentException
is thrown.- Parameters:
n
- the number of elements- Throws:
java.lang.IllegalArgumentException
- if n ≤ 0
-
getExponent
double getExponent()
Get the exponent characterising the distribution.- Returns:
- the exponent
-
setExponent
@Deprecated void setExponent(double s)
Deprecated.as of v2.1Set the exponent characterising the distribution. The parameter value must be positive; otherwise anIllegalArgumentException
is thrown.- Parameters:
s
- the exponent- Throws:
java.lang.IllegalArgumentException
- if s ≤ 0.0
