PanelNaOmit {PooledMeanGroup}

PanelNaOmit

Description

Prepares a panel data set for further calculations by eliminating "NA" and modifying quantity or a vector of the number of time series observations in each group

Usage

PanelNaOmit(dataset, quantity)

Arguments

dataset

a panel data set in the form of stacked time series, containing variables of long-run and short-run relationships (i.e., including differentiated and lagged variables from DiffPanel or LagPanel)

quantity

a vector of the number of time series observations in each group; in practice, it takes the form c(T1,...Tn) since the PMG allows the numbers of time series observations to differ freely across groups (if the number of time series observations in each group is the same, then c(T,...,T) and T=T1=T2=...=Tn

Details

Eliminates "NA" and modifies quantity or a vector of the number of time series observations in each group

Value

$dataset

panel data set for further calculations modified by eliminating "NA"

$quantity

modified vector of the number of time series observations in each group
