Multiple regression is often complicated by collinearity of the predictor variables. This study demonstrates the use of ridge regression as a method for determining those correlated variables which must be eliminated from an analysis and for maximizing the amount of information gained from a set of ...

In fact, we prove that SWAP outputs the true support, the locations of the non-zero entries in the sparse vector, under a relatively mild condition on the measurement matrix. Furthermore, we show that SWAP can be used to boost the performance of any sparse regression algorithm. We ...

Correlated Random Variables of Normal Distribution Let X be a vector of correlated random variables X=[X1,X2,…,Xn]T with joint probability density function fX(x) that are of normal distribution. The elements in the vectors of expected values and the covariance matrix are, respectively, μi ...
As shown in Table 4, we have created a subset of our original data frame where highly correlated variables have been excluded. In the present example, the variable x1 was removed because it has a correlation larger than 0.99 with the variable x2. ...
In a multiple regression analysis, each of the existential issues assessed--hopelessness, sense of dignity, and being a burden to others--was significantly correlated with the will to live. Sense of dignity drives will to live among terminally ill patients Total antibiotic use and prevalence of ...
Hence, in our regression problem for column i of the MSA, Y equals A i and we find a model which explains as much as possible variation in A i using the independent variables in X = M -i . This is repeated for each column i in A separately. As y is a factor with 21 classes,...
Performances of estimators of linear regression model with autocorrelated error term have been attributed to the nature and specification of the explanatory variables. The violation of assumption of the independence of the explanatory variables is not uncommon especially in business, economic and social ...
