Which type of log transformation is most appropriate?

Hello Esri community,

 

I am a doctoral study at DU and I am working on a research project that includes data of Colorado's 178 school districts. Guided by theory, I have compiled a list of variables to run OLS and analyze how these variables interact with its neighboring school districts and predicts school district performance score.

 

Unfortunately, I found some of these variables being moderately/substantially skewed (not normally distributed) and hence need data transformation. I am struggling as these variables show a variety of skewness (moderate to substantial), are either positively/negatively skewed, includes some zero values and are in different formats – percentages, ratios, dollar amounts, count, and sum total. Due to such variability in my data, I am uncertain about which data log transformation would be most appropriate on each of these data types.

 

Any guidance would be very helpful.

 

Thanks.
