This function specifies the input for the isp effect in the formula argument for the function remulateTie or remulateActor. Not to be used independently
isp(param = NULL, scaling = c("none", "std"))List with all information required by `remulate::remulateTie()` or 'remulate::remulateActor()' to compute the statistic.
numeric value, data.frame or function with time parameter. Specifies the value of the effect for the statistic in the REM model
the method for scaling the isp statistic. "none" [default] gives raw value of the statistic at time t, "std" the statistic is standardized per time point.
if param is a data frame, it must have three columns: sender, receiver, and value (numeric), representing the parameter value for thay dyadic pair. The data.frame must contain all pairs of actors or dyads corresponding to the riskset.
if param is a function, it's first argument must be 't', corresponding to the time. The function may have additional arguments.
