\description{
Provides sample datasets. There are 5 different datasets named
M1, M2, M3, M4 and M5 described in the paper references below.
The general model is given by:
\deqn{Y ~ g(B'X) + \epsilon}
}
\section{M1}{

The data follows \eqn{X\sim N_p(0, \Sigma)}{X ~ N_p(0, Sigma)} for a subspace
dimension of \eqn{k = 2} with a default of \eqn{n = 200} data points.
The link function \eqn{g} is given as
\deqn{g(x) = \frac{x_1}{0.5 + (x_2 + 1.5)^2} + \epsilon / 2}{%
      g(x) = x_1 / (0.5 + (x_2 + 1.5)^2) + epsilon / 2}
}

\section{M2}{

\eqn{X\sim N_p(0, \Sigma)}{X ~ N_p(0, Sigma)} with \eqn{k = 2} with a
default of \eqn{n = 200} data points.
The link function \eqn{g} is given as
\deqn{g(x) = (b_1^T X) (b_2^T X)^2 + \epsilon / 2}
}

\section{M3}{

\deqn{g(x) = cos(b_1^T X) + \epsilon / 2}
}
