After doing so, a variable will have a mean of exactly zero but is not affected otherwise: its standard deviation, skewness, distributional shape and everything else all stays the same. After mean centering our predictors, we just multiply them for adding interaction predictors to our data....

Log Transformation, x to log(x), takes the natural logarithm of variables in a data set and is commonly used to reduce right skewness. This strong transformation has a big effect on the shape of the distribution. It can’t be applied to zero or negative values. Taking the square: x →...
There doesn’t seem to be a simple function in R for creating bihistograms, butStrictlyStatsuggests overlaying two histograms on top of each other, for the same effect. For the code using either ggplot or base graphics, seethis article the R-Bloggers site. You can also find an online calc...
In this study, we explored innovative approaches to sustainable fashion design, focusing on the increasingly prominent issue of sustainability in the global fashion industry. By analyzing consumer feedback in online communities, particularly through a sy
Immersion as an umbrella experience and embodiment are regarded as primary advantages of virtual reality and its capability to lead to other reflective exp
Initially, data normality was confirmed using skewness and kurtosis measures. A two-step process was then followed, beginning with confirmatory factor analysis (CFA) and proceeding to SEM to examine the hypothesized relationships. The fit indices for the proposed measurement model (χ2 = 487.21, df...
2011). But could personality help find and automatically model other characteristics of tourists, such as their motivations, and travel-related preferences and concerns when traveling in leisure? Can it be used to mitigate conflicting preferences in groups of tourists? Motivation has long been studied...
The theory is widely used in finance to analyze an extensive collection of funds and estimate portfolio distributions and traits for returns and risk. Skewness The asymmetry of a distribution is measured by skewness. Types of skewness A distribution can represent positive (right), negative (left)...
(2020c) suggest a sample size of N = 93 is required to identify a main effect on children's trust in the robot as well as an N = 780 to find a main effect of the manipulation on children's closeness toward the robot. In terms of H2, a sample size of N = 7 would be needed ...
