The term "statistical significance" often pops up in research and data analysis, but what does it actually mean? At its core, statistical significance is a way to express how confident you can be that your findings are not just a fluke. It’s like a stamp of reliability on your results,...
Statistics: How can I account for clustering when creating imputations with mi impute? (Updated 26 June 2017) Statistics: How can I combine results other than coefficients in e(b) with multiply imputed data? (Updated 26 June 2017) Statistics: Where can I find a description of the various...
Descriptive statistics are your starting point: Measures of Central Tendency Mean: The average value in your dataset. Median: The middle value when your data is ordered. Mode: The most frequent value in your dataset. Measures of Spread Range: Difference between the highest and lowest data points...
Records for which charge data were incomplete were completed by using single mean imputation, also inflation-adjusted. Descriptive data are presented as mean 卤 standard deviation (SD). Results Of 102 CE patients, 35 had available hospital charge data15 who underwent successful primary closure at ...
We include all possible information in our imputation model, meaning all the variables in our dataset, and impute the missing data using the predictive mean matching method, and then analyze each dataset and pool the results. Our workflow will look like this Adapted flowchart from van Buuren (...
Existing command collapse now allows new statistics semean, sebinomial, and sepoisson for obtaining the standard error of the mean. Existing command destring allows new option dpcomma to convert to numeric form string representation of numbers using commas as the decimal point. Concerning existing...

The home is also a place where adults spent most of their total wear time per day, and it may thus be that when total time spent at a location increases, time spent in MVPA at that location also increases. Obviously, this does not mean that staying at home is the solution for ...
Note that our assumptions measurement errors in GDP and lights also imply that the standard errors of the estimated coefficients are biased. While the sign is indeterminate, it can be shown that the resulting t-statistics are underestimated. The standard errors of the estimated relative attenuation ...
