Abetacoefficient shows the volatility of an individual stock compared to the systematic risk of the entire market. Beta represents the slope of the line through a regression of data points. In finance, each point represents an individual stock's returns against the market. Beta effectively describe...
In this paper, we propose a beta regression model with multiplicative log-normal measurement errors. Three estimation methods are presented, namely naive, calibration regression and pseudo likelihood. The nuisance parameters are estimated from a system estimation equations using replicated data and these ...
The zero-one inflated beta regression model can be extended to a multilevel model, where the information is clustered hierarchically at several levels. This is a recent line of research in the field of mathematical statistics, which is currently under development. In this paper we have carried ...
Generalized linear mixed models (GLMMs) are a cornerstone data analysis strategy in behavioral research because of their robustness in handling non-normally distributed variables. Recently, their integration with ordered beta regression (OBR), a novel statistical tool for managing percentage data, has op...
It goes without saying that each has a different way of being calculated. Alpha is formulated using thecapital asset pricing model (CAPM)formula which considers an investment's actual return, risk-free rate, and beta. Beta, on the other hand, is calculated through regression analysis, which ...
Beta reflects a company’s business risk over the period used in the regression model, which can be misleading if the company has undergone significant changes in terms of its business model, target customer, etc. Lastly, beta is typically based on the historical average financial leverage (i....
Thus, we also identified rare species (those with fewer than 25 individuals) and common species in the plot, and ran separate regression analyses with LCBD for rare and common species. The packages PCNM, "spacemakeR", "packfor" and "vegan" in R were used to conduct the dbMEM, forward ...
