### Mean score of the Composite Variable

I have three items(Likert scale from 5 to 1) measuring opportunity recognition. I was getting negative cronbachs alpha value. Hence, I reverse-coded and got the Cronbach's alpha of 0.83. I will be ...

### Why use integrals when building exponential composite functions?

I recently read this paper, which describes a generalisation for statistical exponential decay models used in ecology. Essentially, the parameter $k$ of the exponential decay function $f(x) = ce^{-kx}$...

### Obtaining confidence intervals from composite defined functions

Assume you have a set of $n$ independent random variables $X_1, X_2, \dots, X_n$ with unknown distribution and mean (finite) values $\mu_1, \mu_2, \dots, \mu_n \in \mathbb{R}$. Moreover, there are $n$ ...

### Suggest a reasonable approach to combine the following variables into a single vector

I have 9 variables, namely BMI, waist-to-hip ratio (WHR), healthy-diet (HD: a score of 0 to 4, close to 4 indicates healthy), waist circumference (WC), neuroticism score (NS), body fat percentage (BF),...

### Can Composite Reliability (CR) be used for attenuation correction in meta-analysis?

I'm trying to conduct a meta-analysis on correlation using Spearman's disattenuation formula: rx'y' = rxy/sqrt(rxx*ryy). Can composite reliability (CR) instead of Cronbach's α be used in this formula? ...
