It indicates that researchers need to identify one or more variables, known as the instrumental variables or instruments, in using instrumental variable estimation. It shows the application of instrument variable estimation during classic study of treatment of acute myocardial infarction (AMI).Penrod...
A case study is presented, where the paper and pencil environment and the technological one are combined together and designed to face a subtle mathematical problem: how to choose the dependent Vs independent variables in modelling situations? We show how the combined approach allows to pose the ...

Mathematically, the p-value is calculated using integral calculus from the area under the probability distribution curve for all values of statistics that are at least as far from the reference value as the observed value is, relative to the total area under the probability distribution curve. Sta...
There are so many options, so the one you choose depends on what kind of data you have and what you want to display. If you want to display a relationship between data, you can use a bar graph. You will need to use a pie chart to represent how various categories are proportioned ...
In addition, to address the potential estimation bias resulting from reverse causality in the model, the key explanatory variables are delayed by one step, taking into account the government’s limited focus on environmental issues. Finally, fiscal income is leveraged as an instrumental variable when...
Table 8 shows the results of the fourth estimation, and the coefficient of the severity of the famine is negative and significant, which shows that after controlling for the instrumental variables, the CEO’s experience of the severity of the famine in early life still has an impact on firm ...
A target rate is a key interest rate that a central bank uses to guide monetary policy toward the desired economic outcomes. A central bank can choose its target based on official discretion or specific policy rules with the intent of influencing economic variables, such as employment or inflatio...
To address this problem, they used the instrumental-variables method. The results showed that every 4 kg/m2 increase in BMI increased the risk of coronary heart disease by 26%, and the instrumental variables method revealed a 52% increase in risk. A study by Larsson et al. used the ...
However, in theory, there may still be omitted variables that affect enterprise upgrading. Therefore, if the impact of unobservable factors were not controlled, the estimate results of the OLS would be biased. This study mitigated potential endogeneity through instrumental variables to lower the ...
