Purpose - The purpose of this paper is to examine ABC success determinants in mature ABC sites.Design/methodology/approach - The study surveys 65 users of an ABC system in service and manufacturing firms.Findings - The stepwise regression results indicate that top management support is the key ...
the value of complements matters: A skill is more valuable, if its complements are of high value, too. Thirdly, we show that the value of a skill is relative, as one and the same type of skill can have different premia, if combined with a different set of skills that a worker ...
In recent years, the diagnosis of Down syndrome has become widespread and recommended in the fetal DNA in a mother’s blood analysis. However, the evaluation of DS with first-trimester screening is still widely used both in the world and our country because of its very expensive and performed...
Quantitative research is the backbone of evidence-based decision-making. Its core purpose is to transform raw data into actionable insights. Researchers can uncover hidden patterns, trends, and relationships that might otherwise go unnoticed by employing statistical methods to analyze numerical information....
Conversely, in higher-income economies, the role of equids is considerably more individually specialised and often less essential for supporting basic livelihoods since they mainly fulfil sports, racing, leisure, tourism, and recreation roles [64,65]. However, many of the equids in such economies ...
As a general rule of thumb, I would recommend to start with Logistic Regression. Logistic regression is a pretty well-behaved classification algorithm that can be trained as long as you expect your features to be roughly linear and the problem to be linearly separable. You can ...
Consider the simple linear regression model y = \beta_0 + \beta_1x + \epsilon where the intercept \beta_0 is known. a. Find the LS estimator of \beta_1 for this model. b. What is the variance of the A) What are important principles of least square estimation for the linear regres...
In terms of the wound healing, Hollander Wound Evaluation Score (HWES) was assessed on postoperative day 14. We performed multiple regression analysis using stepwise method to identify the factors affecting HWES. Variables considered in the analysis were age, sex, body mass index (kg/m2), Hb...
I think the regression model can be improved, but I don't know what I have to do more. Please give me some advice after seeing the plot(reg) output. I've done log transformation and square root transformation of yy. regression r multiple-regression residuals stepwise-regression Shar...
In the above formula, X includes independent variables, and Y is the HFC. The independent variables were included in the model according to a forward stepwise approach. For this purpose, first the socio-demographic variables of the household’s head, that is, age, gender, employment status, ...
