using the first method above, or COMPUTE arcpct ARSIN (SQRT (var2/100)) 45 / ARTAN (1). For example, if the values of VAR2 are percentages : COMPUTE arcpct 2 ARSIN (SQRT (var2/100)). In both cases, percentages should first be changed to proportions by dividing the percentage by 100. You can divide a variable with percentages by 100 within the arcsine transformation command without creating a new variable with proportions. The two most common methods for transforming percents, proportions, and probabilities are the arcsine transform and the logit transform. Which transformation is most appropriate for percentage? where X indicates the percent value to be transformed. You can simply perform arcsin transformation in excel workbook itself with a formula =DEGREES(ASIN(SQRT(X/100))). This transformation stretches the extremities of the domain (near 0 and. Properly formatted and validated data improves data quality and protects applications from potential landmines such as null values, unexpected duplicates, incorrect indexing, and incompatible formats. First proposed by Fisher, the arcsine transform is one way to represent proportions. Transformed data may be easier for both humans and computers to use. Now, we have got the complete detailed explanation and answer for everyone, who is interested!ĭata is transformed to make it better-organized. This is a question our experts keep getting from time to time.
