Abstract

Verification of causal analysis research that examines the effect of one or several exogenous variables on endogenous variables directly or indirectly at the data processing stage used Path Analysis statistical techniques that require the accuracy of use to determine the path coefficient, especially the minimal exogenous variable data has a scale interval measurement. The purpose of this study. To offer the use of R software that is free (open source) and does not require a license for the user in the ordinal scale data transformation process into more efficient intervals compared to other software. which is generally paid and requires a license for the user ... This is related to data collection results using a Likert scale based questionnaire that produces ordinal types. The method used. Is a survey research with a quantitative approach. To overcome this problem, before calculating the path coefficient, the transformation of data from ordinal to interval is first performed using the Successive Interval Method (MSI) approach and for the efficiency of the results of MSI data transformation, the writing of this paper offers calculations using software assistance R. The conclusion of this research is the results of R application in the calculation of survey data of exogenous variables user loyalty shows efficient time and speed of processing until obtained simultaneously both interval data for each item grading attitude attitude and the total score of interval data for each respondent.
