The present study provides valuable insight into the use of path analysis which is an extension of multiple regressions for testing the hypotheses in data related to diabetes knowledge, attitudes, self-management, and QoL among people with T2DM.
Furthermore, the results were virtually identical in a case only, logistic regression analysis for testing for differences in the associations with tumour subtypes which included only individuals with known tumour characteristics (results not shown).
The concept of residuals is not well defined in Tobit regression, and methods for testing model validity were not available given the slightly unusual truncated nature of the conditional distribution of outcomes.
We included interaction terms between estimated glomerular filtration rate and treatment strategy in regression models to test for modification of the treatment effect by baseline estimated glomerular filtration rate.
The P values in Table 1 are for regression models testing for differences in the mean values for each risk factor between participants classified with and without the syndrome.
These are then treated as covariates in the logistic regression model, providing a basis for testing for association with disease, adjusted for the effects of underlying population structure.
Testing procedure for testing a change in a linear regression with equidistant design is considered.
In addition we performed multiple regression analyses testing for a positive or negative correlation of grey and white matter volume with number of manic or depressive episodes, duration of illness, existence of psychotic symptoms, or treatment with lithium or antipsychotics.
Persons with one or more psychotic-like symptoms (designated as PSQ screen-positive cases) were compared with the remainder of the sample in univariate and multivariate logistic regression analyses, testing for associations with socio-demographic indices, PTEs (categorized as 1-2, 3-4, 5-6 and 7 or greater) and PTSD (present-absent).
For example, in the regression model tested by Collier and Hoeffler [ 61], none of their proxy measures for grievance relates to social conditions in general, and to health in particular.
