You can set the use.value.labels argument to FALSE, if you wish to not convert value labels variables to R factors. Also, to.data.frame argument can be set to TRUE to receive output in data frame display. 2. STATA FILES You can import stata files to R via foreign package through the...
Letx(j)refer to thexin ascending order forj= 1, 2, ...,n. Letw(j)refer to the corresponding weights ofx(j); if there are no weights,w(j)= 1. Let N =Σnj=1w(j). To obtain thepth percentile, which we will denote asx[p], we need to find the first indexisuch thatW(i)...
Figuring out missing data is just the first step of the problem. You will have to perform additional coding to replace missing values with imputations (that is using mean, median to replace missing values). This process can be time-consuming as it requires researchers to manually match columns...
To limit bias and manage item non-response, multiple imputations using Stata 15 with chained equation were used for all control measures, listed below (Allison, 2001). Following von Hippel (2007), respondents with missing values on the dependent variable (influenza vaccination) were included in ...

In the United States, quant trading positions are most prevalent in big financial hubs such as New York and Chicago, and areas where hedge funds tend to cluster, such as Boston, Massachusetts, and Stamford, Connecticut. Globally, quant traders may find employment opportunities in major financial ...
The continual reassessment method (CRM) is a model-based design for phase I trials, which aims to find the maximum tolerated dose (MTD) of a new therapy. The CRM has been shown to be more accurate in targeting the MTD than traditional rule-based approaches such as the 3 + 3 design...
In the violin plot, we can find the same information as in the box plots: median (a white dot on the violin plot) interquartile range (the black bar in the center of violin) the lower/upper adjacent values (the black lines stretched from the bar) — defined as first quartile — 1.5...
He then goes into some detail about how to interpret coefficients, compare different models, and so on. Quite useful. However, how much variance does the model account for? AStata page on logistic regressionsays: Technically,R2R2cannot be computed the same way in logistic regression as...
Recent work has drawn attention to the relationship between empowerment and women’s mental health (Leight et al., 2022, Bliznashka et al., 2024). Leight et al. (2022) find that in Burkina Faso, empowerment, measured by pro-WEAI, is associated with lower maternal depression and stress. ...
