In our study we are testing the hypothesis that financial risk is significantly correlated with the banks financial performance. The measure for financial risk is credit risk and liquidity risk. In some studies one single study includes both credit risk and liquidity risk and their correlations with financial performance. We want to include both data in our metaanalysis. like this 1 study will be taken twice.
Does it violets the assumption of meta analysis or can we adopt this approach as the variables undertaken are different. Please help.
