Statistical analysis of sparse approximate factor models [PDF]
The authors consider a sequence of \(n\) i.i.d.~observations of a \(p\)-dimensional random vector \((X_i)\), having the factor structure \(X_i=\Lambda\,F_i+\epsilon_i\), where \(\Lambda\) is the loading \(p\times m\) matrix, \(F_i\) is the vector of centred factor variables and \(\epsilon_i\) are the errors -- the idiosyncratic variables. The dimension

Multivariate statistical analysis of yield-determining factors [PDF]
This study is aimed at developing a multivariate statistical method to identify yield-determining factors and to evaluate their relative magnitude. Principal component analysis was used to summarize the rice growing environment in a “hydromorphic” field into a number of factors which may affect the yield performance. Four major factors were recognized;
