Calculating confidence intervals in R is a handy trick to have in your toolbox of statistical operations. A confidence interval essentially allows you to estimate about where a true probability is based on sample probabilities at a given confidence level compared to your null hypothesis. The confide...

To construct a county-year sample, we use the Federal Procurement Data System-Next Generation database to compute the value of federal procurement contracts executed at the county level for each county-year. We adopt a difference-in-differences design by regressing the value of federal procurement...
First, using the two-step method to compute IMR may further amplify errors during the second-stage estimation. Second, adjusting clustering using the two-step method is difficult. Therefore, for robustness, we use the maximum likelihood estimation method to estimate the treatment effects model to ...
For example, using a synthetically created firm size distribution in the manufacturing industry, we exploit the fact that France and Germany have different size-based disclosure thresholds to compute the simulated proportions of private firms subject to disclosure – also known as the “standardized ...
prob: a boolean flag indicating if we want to include in the output the probability of each prediction outputtableprob: the name of the output table where the probability of each prediction will be stored 6. Evaluate the model Using generated predictions for the test dataset, I compute a few...
ii. Which is more detrimental to a model? Why? b. Given a model "infected" wi How would a Q-Q plot look if the disturbance terms have a kurtosis much smaller than three but no skewness? a. Points would generally fall above the line in both tails. b. Points would generally...
(four studies). In such cases, the comparator group was used to compute more than one effect size and, in consequence, the estimates of these effect sizes are correlated. Because we were interested in testing for the association between operational regime and effect size, we did not aggregate...

The heart of calculating drawdown lies in the following steps. You need to define a function to compute the drawdown using the provided stock price data. Here is the code explained line by line: Define a function name calculate_drawdown whose input is a data frame of a stock historical price...
