Changes in Version 0.3-2 o Bug fix so that weights/offset can actually be used. Changes in Version 0.3-1 o Fixed bug in computation of R-squared values and Wald statistic for two-stage least squares. Changes in Version 0.3-0 o Added new formula functions trend() and harmon() that allow convenient specification of linear or cyclical patterns. Changes in Version 0.2-3 o fixed bug when lagged variables are used in instrumental variables regression. Changes in Version 0.2-2 o added CITATION file Changes in Version 0.2-1 o enhanced documentation ?dynlm Changes in Version 0.2-0 o added support for instrumental variables regression (two-stage least squares) via formulas like dynlm(y ~ x1 + x2 | z1 + z2 + z3, data = mydata) where z1, z2, z3 are the instruments. o enabled specification of multiple lags via formulas like dynlm(y ~ L(x, 0:4), data = mydata) where y is regressed on x and lags 1 through 4 of x. o fixed bug in time properties when there were leading NAs in the data
