Read data in columns (X_1 .. X_N). The j\-th equation is specified by a function f_j(x1,x2...) using variables names x1,x2,..,xN for the first, second...N\-th column of data. The f_j(x1,x2,...)'s are assumed i.i.d. according to a multivariate gaussian distribution. .SH OPTIONS .TP \fB\-O\fR type of output (default 0) .TP 0 parameters .TP 1 parameters and errors .TP 2 and residuals .TP 3 parameters and variance matrix .TP \fB\-V\fR variance matrix estimation (default 0) .IP 0 1 < J^{\-1} > 2 < H^{\-1} > 3 < H^{\-1} J H^{\-1} > .TP \fB\-e\fR minimization tolerance (default 1e\-5) .TP \fB\-v\fR verbosity level (default 0) .TP 0 just results .TP 1 comment headers .TP 2 summary statistics .TP 3 covariance matrix .TP 4 minimization steps .TP 5 model definition .TP \fB\-F\fR input fields separators (default " \et") .TP \fB\-h\fR this help .SH AUTHOR Written by Giulio Bottazzi .SH "REPORTING BUGS" Report bugs to .PP .br Package home page .SH COPYRIGHT Copyright \(co 2001\-2015 Giulio Bottazzi This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License (version 2) as published by the Free Software Foundation; .PP This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
