The Poisson Regression Model (PRM) is one of the benchmark models when analyzing the count data. The Maximum Likelihood Estimator (MLE) is used to estimate the model parameters in PRMs. However, the MLE may suffer from various drawbacks that arise due to
The unit to be used is calledStandard Error. It’s labeled “Standard” because it serves as a standard unit. And it’s labelled “Error” because we don’t expect oursample statisticvalues to be exactly equal to the populationparameter; there will be some amount of error...
One of the fundamental questions about human language is whether all languages are equally complex. Here, we approach this question from an information-theoretic perspective. We present a large scale quantitative cross-linguistic analysis of written language by training a language model on more than ...

Mendelian randomization (MR) studies using Genetic risk scores (GRS) as an instrumental variable (IV) have increasingly been used to control for unmeasured confounding in observational healthcare databases. However, proper reporting of methodological issues is sparse in these studies. We aimed to revi...
That variable is the task-relevant maturity (TRM) of the subordinates, which is a combination of the degree of their achievement orientation and readiness to take responsibility, as well as their education, training, and experience. When the TRM is low, the most effective approach is one that...
For instance, you might create a variable for gender, which takes the value 1 if the person is male and 0 if the person is female. The 0 and 1 have no numeric meaning but function simply as labels in the same way that you might record the values as M or F. However, researchers ...
Afutures contract, or simply futures, is an agreement between two parties for the purchase and delivery of an asset at an agreed-upon price at a future date. Futures are standardized contracts that trade on an exchange. Traders use futures to hedge their risk or speculate on the price of a...
