Construction and analysis of the path coefficients. ISSN bt The present article contains an explanation of the Path coefficients, from a mathematical-statistical point of view. For example, the indirect selection of variables related to a response variable requires the identification of simple characteristics highly associated with the dependent variable. This identification is usually based on the correlation analysis; which determines an index correlation coefficient or reference about the relationship between variables, but this analysis abd restricted in the sense that it only provides information between variables one by one it means that, it is information between pairs of variables, so, many characteristics that apparently have no relation with the dependent variable, is due to the fact that the effects of the independent variables are not direct; but they are related indirectly and the analysis of path coefficients, is a very useful technique to determine these effect-cause relationships and the magnitude of said coefficients; they precisely provide information on the relationship, based on direct and indirect effects.

This method is well known in the field of agronomy and regdession was already used in several crops, so, as an example its application will be briefly on the crops of what do you mean by regression and correlation analysis ajipa tuber pachiryzus ajipa. Then, a regression analysis is performed first on the yield what is relational in dbms pods in ajipa crops, rescuing the most statistically significant variables at level of 0.

The results offered by this analysis will be more precise at the application of the problem. Palabras clave : Path coefficients; correlation; dependence; regression; techniques of interdependence. Servicios Personalizados Revista. Similares en SciELO. Como citar este artículo.
