It also supports distributed shuffle join for multiple large tables so as to handle complex queries.The Doris query engine is vectorized, with all memory structures laid out in a columnar format. This can largely reduce virtual function calls, improve cache hit rates, and make efficient use of ...
Many constructs in management studies, such as perceptions, personalities, attitudes, and behavioral intentions, are not directly observable. Typically, empirical studies measure such constructs using established scales with multiple indicators. When the scales are used in a different population, the items...
We did not consider χ², t, and F tests that were used in regression analysis or model fitting, because statistical tests of regressions are often not presented fully and because model fitting (e.g., in structural equation modeling) normally is aimed at not rejecting the null hypothesis. ...
In the first part of our study, we identified a large set of companies listed on the European, British, US, Canadian, Australian and New Zealand stock exchanges and operating in the “addiction sectors”. More specifically, we investigated their voluntary reporting practices and the actions implem...
The Doris query engine is vectorized, with all memory structures laid out in a columnar format. This can largely reduce virtual function calls, improve cache hit rates, and make efficient use of SIMD instructions. Doris delivers a 5–10 times higher performance in wide table aggregation scenarios...
The Doris query engine is vectorized, and all memory structures can be laid out in a columnar format to achieve significant reductions in virtual function calls, improved Cache hit rates, and efficient use of SIMD instructions. Performance in wide table aggregation scenarios is 5–10 times higher...
The APA mentions that ES expressed in original units allows for an easier interpretation (“e.g., mean number of questions answered correctly, kilograms per month for a regression slope”) [13] (p. 89), but focuses primarily on statistical estimates. There are entire courses devoted to ...
Ho and Taylor (2007) employed multiple regression analysis to investigate the factors influencing sustainability reporting in Japan and the United States, demonstrating a statistically significant positive correlation between business size and sustainability disclosure. This result is similar to the findings ...
This study examines the relationship between environmental, social, and governance (ESG) practices, financial reporting quality, and ownership structure in Chinese listed companies, based on a panel dataset of 1841 firm-year observations from 2016 to 2020. Using three types of panel regression analyses...
We also performed a classical CPH multiple regression (using lifelines v0.25.11 [50]), which yielded HRs for each feature in the model. Additionally, we used eXtreme Gradient Boosting (XGB, using xgboost v1.3.3) as a representative ML technique for survival analysis [14]. We chose this ...
