[tab] With no arguments, <lit>$vcv</lit> returns a square matrix 
[tab] containing the estimated covariance matrix for the coefficients of
[tab] the last model. If the last model was a single equation, then you
[tab] may supply the names of two parameters in parentheses to retrieve
[tab] the estimated covariance between the parameters named
[tab] <argname>s1</argname> and <argname>s2</argname>.

[tab] Computes one of the Bessel function variants for order
[tab] <argname>v</argname> and argument <argname>x</argname>. The return
[tab] value is of the same type as <argname>x</argname>. The specific
[tab] function is selected by the first argument, which must be
[tab] <lit>J</lit>, <lit>Y</lit>, <lit>I</lit>, or <lit>K</lit>. A good
[tab] discussion of the Bessel functions can be found on Wikipedia; here
[tab] we give a brief account.

[tab] case <lit>J</lit>: Bessel function of the first kind. Resembles a
[tab] damped sine wave. Defined for real <argname>v</argname> and
[tab] <argname>x</argname>, but if <argname>x</argname> is negative
[tab] then <argname>v</argname> must be an integer.

[tab] Numerical maximization via the method of Broyden, Fletcher, Goldfarb
[tab] and Shanno. The vector <argname>b</argname> should hold the initial
[tab] values of a set of parameters, and the string <argname>s</argname>
[tab] should specify a call to a function that calculates the (scalar)
[tab] criterion to be maximized, given the current parameter values and
[tab] any other relevant data. If the object is in fact minimization, this
[tab] function should return the negative of the criterion. On successful
[tab] completion, <lit>BFGSmax</lit> returns the maximized value of the
[tab] criterion, and <argname>b</argname> holds the parameter values which
[tab] produce the maximum.

[tab] The parametrization \app{gretl} uses for the Gamma random variate
[tab] implies that its density function can be written as

[tab] where $k>0$ is the shape parameter and $\theta>0$ is the scale
[tab] parameter.
