Re: [Gretl-users] Computing t-statistics from P-values

Dear all, I have another preoccupation, I'm carrying-out a meta analysis and have to regress 't-statistics" on some independent variables. However most studies present "P-values" beside regression coefficients. Is there any easy way of transforming these P-values into t-statistics of two-tailed distributions?.

Given a panel dataset of dimension N x T you can append data with a series length of N or T and the added data will be repeated as appropriate to complete the panel.
