Arguments
g
the temporal interaction function. It must accept
two arguments, the first one being a vector of time points, the
second one a parameter vector. For marked twinstim, it must
accept the type of the event (integer code) as its third
G
a primitive of $g(t)$ (with respect to time). It must
accept the same arguments as g, for instance a vector
of time points (not just a single one).
deriv
optional derivative of $g(t)$ with respect to
the parameters. It takes the same arguments as g but
returns a matrix with as many rows as there were time points in the
input and npars columns. This derivativ
Deriv
optional primitive of deriv (with respect to
time). It must accept the same arguments as deriv, g and
G and returns a matrix with as many rows as there were time
points in the input and
npars
the number of parameters of the temporal interaction
function g (i.e. the length of its second argument).
validpars
optional function taking one argument, the parameter vector, indicating if it
is valid. This approach to specify parameter constraints is rarely
needed, because usual box-constrained parameters can be taken into
account by using L-BFGS-B as th
