_D_e_s_c_r_i_p_t_i_o_n:

     This library provides functions related to the skew-normal
     probability distribution, both for the univariate and the the
     multivariate case.

_F_U_N_C_T_I_O_N_S:

     The functions of the scalar case section are: `dsn', `psn', `qsn',
     `rsn', `T.Owen', `cp.to.dp',  `dp.to.cp', `zeta',
     `gamma1.to.lambda', `sn.cumulants', `sn.em', `sn.2logL.profile',
     `sn.mle', `sn.dev', `sn.dev.gh'.

     The functions of the multivariate section are: `dmsn', `rmsn',
     `plot.dsn2', `msn.quantities',  `msn.conditional', `msn.marginal',
     `plot.msn.cond', `msn.fit', `msn.mle',  `msn.dev', `msn.dev.grad',
     `msn.moment.fit', `num.deriv'.

_R_E_Q_U_I_R_E_M_E_N_T_S:

     R 1.0.1

_V_E_R_S_I_O_N:

     You are using version 0.22 (2000/09/15). The most recent version
     of the library can be obtained from the WWW page: <URL:
     http://www.stat.unipd.it/~azzalini/SN> which also contains other
     related material

_M_A_N_U_A_L:

     There is no manual for this version (and possibly there will never
      be one). All documentation is on-line, apart for the papers
     listed below,  which provide background information. Some
     functions are not documented.

_A_U_T_H_O_R:

     Italy. Please send comments, error reports, etc. to
     azzalini@stat.unipd.it

_A_C_K_N_O_W_L_E_D_G_E_M_E_N_T_S:

     Many thanks go to Antonella Capitanio for testing the procedures,
     and to Brian Ripley and Martin Maechler for useful advice on R. 
     The function `num.deriv' is based on a similar function written 
     by Monica Chiogna.  This software and part of the associated
     theoretical work has been developed  while the author was at the
     Nuffield College, Oxford, under the Jemolo  Fellowship scheme; the
     generous support of the  college is gratefully  acknowledged. 
     Additional support for the development of the theoretical research
     work has  been  provided by the "Consiglio Nazionale delle
     Ricerche" of Italy, grant  no.97.01331.CT10.
