dynformula, pht, plm.data, and pvcovHC are deprecated functions which could be removed from plm in a near future.
pvcovHC(x,...)plm.data(x, indexes =NULL)dynformula(formula, lag.form =NULL, diff.form =NULL, log.form =NULL)## S3 method for class 'dynformula'formula(x,...)## S3 method for class 'dynformula'print(x,...)
Arguments
x: an object of class "plm",
...: further arguments.
indexes: a vector (of length one or two) indicating the (individual and time) indexes (see Details);
formula: a formula,
lag.form: a list containing the lag structure of each variable in the formula,
diff.form: a vector (or a list) of logical values indicating whether variables should be differenced,
log.form: a vector (or a list) of logical values indicating whether variables should be in logarithms.
data: a data.frame,
Details
dynformula was used to construct a dynamic formula which was the first argument of pgmm. pgmm uses now multi-part formulas.
pht estimates the Hausman-Taylor model, which can now be estimated using the more general plm function.
