This article describes a dataset that allows to explore the determinants and moderators of athletes’ decision to enter in tournaments endowed with a monetary prize. Specifically, the dataset contains variables that describe athlete's short-term momentum (i.e., performance streak in the tournaments recently entered) and long-term momentum (i.e., performance streak in the same tournament across seasons), which permits an in-depth analysis of how past performance trajectory drives self-selection into tournaments. The dataset consists of 54,915 self-selection decisions that golfers have taken over an eleven-year period (1996-2006) when deciding to participate in PGA Tour tournaments.

Out-of-Sample Validation

This chapter deals with the validation of classification models. The role of validation is to dismiss the concerns about overfitting, which happens when we develop a complex model in order to fit the current data but that model fails later to fit new data. The example deals with churn modeling, already mentioned in Chap. 8.

In this chapter, we explain how to introduce categorical variables in a regression analysis, coding the categories with dummy variables. This is needed in most of the applications of regression analysis, since the samples on which we collect our data are typically partitioned into groups. In the example, we use a dummy variable to code gender, which allows us to include the comparison between genders in the analysis in an easy way.


Multiple Regression

July 2019

This chapter and Chaps. 5 to 7 cover multiple regression analysis. The discussion is oriented to practical business applications. Most technicalities have been skipped, and the mathematics have been simplified to the indispensable. So, if you have already followed a Statistics course, you may find that the attention paid to the different aspects of the regression analysis differs from what you found there.


Nonlinear Trends

In many applications of time series analysis, a linear trend is not adequate for the data. In this chapter we discuss some alternatives, within the scope of Excel. In the example, we use a quadratic trend and additive seasonals for modeling the variation of monthly sales of a beer brand. We also perform an exercise of out-of-sample validation based on the last year’s data.


Testing Regression Coefficients

This chapter continues the discussion of regression analysis engaged in Chaps. 3 and 4. We have seen that the regression coefficients are reported with extra information, which we have not discussed yet. How can we use this information? In particular, we explain here how to use the confidence limits and the p-values to decide about statistical significance. The example of this chapter, which deals with the analysis of the impact of the prices on market share, illustrates the interpretation of the p-values.

The last chapter of this book presents the Holt-Winters forecasting method, in two versions, with additive and with multiplicative seasonals. The example is an application of Holt-Winters with multiplicative seasonals to data on monthly sales of a meat product at an Ecuadorian supermarket chain.

... There has been growing interest in adopting advanced data science and artificial intelligence techniques to gain deeper insights into golf performance [9]. These data can be leveraged using sophisticated statistical and machine learning models to uncover patterns and make data-driven decisions [10,11]. One key area of focus has been the use of sensorbased technologies and wearable devices to capture real-time data on a golfer's movements, club dynamics, and shot trajectories [12]. ...

A rotina das pessoas vem sendo impactada irreversivelmente pela expansão da conectividade propiciada pelo avanço da presença da internet no cotidiano dos indivíduos, favorecendo a interatividade e, sobretudo, as iniciativas de apoio a ideias, conceitos, produtos e, nesse sentido, negócios (Castells, 1999). Em meio às mudanças percebidas, as startups surgiram apresentando uma dinâmica diferenciada dos padrões organizacionais anteriormente praticados, destacando-se o modelo de liderança compartilhada, embora diferentes condicionantes têm sido elencados como potenciais influenciadores ou drivers para o sucesso de crowdfundings (Janků & Kučerová, 2018;Moleskis et al., 2019;Wang et al., 2020). ...

... Over the past fifteen years, scholars have started paying attention to crowdfunding in Africa; an online crowd participatory financing that has been in practice in the developed world for way back, but new to the African continent in its online form. Although more entrepreneurial ventures are using the power of the crowd to get financed (N'Guessan et al., 2017), the use of crowdfunding as an alternative method of raising fund by SMEs in Africa is still at its nascent stage as it only represents less than 0.1% of the total worldwide crowdfunding market (Olafusi et al., 2022). Furthermore, while many platforms are presently active, non-African-based platforms are able to collect more funds for projects in Africa (N'Guessan et al., 2017). ...

... For instance, salespeople with higher moral identity are less likely to engage in customer-directed sabotage in response to lower levels of customer justice, as they intrinsically follow the mantra "treat the customer as you would want to be treated" (Skarlick et al. 2016, p. 111). With regards to coworkers, research shows that an ethical and moral work environment leads to the formation of internal social capital, where team members sincerely work together and share a mutual commitment towards organizational goals (Pastoriza et al. 2015). ...

... This makes angiosperms a powerful model system for studying the underlying drivers that shape genome size evolution and its distribution across the globe. The recent increase in the use of flow cytometry in botanical studies has led to a substantial accumulation of standardized genome size data across wide phylogenetic and geographic scales (Garcia et al., 2014;Leitch et al., 2019;Šmarda et al., 2019;Zonneveld, 2019). Given that consistent geographic data have recently become available for most known species through the World Checklist of Vascular Plants (WCVP; Govaerts et al., 2021), it is now possible to examine hypotheses seeking to understand the causal links between angiosperm genome size, distribution, and environment at a global scale. ...

... The Asteraceae family also records a higher number of useful medicinal plants which were already manifested in Nepal (Kunwar et al., 2018). The other reason for the highest number of species from the Asteraceae might be due to the largest plant family comprising 1600-1700 genera and 24,000-30,000 species worldwide (Funk et al., 2005;Vallès et al., 2013). Moreover, Asteraceae taxa can assume almost every life form: herbs, succulents, lianas, epiphytes, trees, or shrubs, and they are found in all continents, except Antarctica (Funk et al., 2005). ...
