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...

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...
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 ...
Deep Learning: Inverse short-time Fourier transform layer This release introduces a learnable signal processing layer that enables you to compute the inverse short-time Fourier transform within a deep learning network. The istftLayer object is available from the command line and from the Deep Network...
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...
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...
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...
Four characteristics are needed to fully describe a frequency distribution: a measure of central tendency (e.g., mean, median, mode), a measure of variation, skewness (e.g. symmetric, skewed left, skewed right), and coefficient of kurtosis. The u...
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 ...
