\title{Class "asinht"  }
\description{ Inverse hyperbolic sin transfromation is defined by the function
\deqn{f(parameter,a,b)=sinh^{-1}(a*parameter)*b}
}
\section{Objects from the Class}{
Objects can be created by calls  to the constructor
\code{asinht(parameter,a,b,transformationId)}

}

\note{ The inverse hyperbolic sin transformation object can be evaluated using the eval method
 by passing the data frame as an argument.The transformed parameters are returned as a matrix with a single column. (See example below)  }
