## differences in lambda_z calculation between PHX and PK package in R [Software]

Dear All,

some time ago I discovered the difference between PHX and 'PK' package in R regarding lambda_z calculation for sparse dataset analysis.

My question is which one looks more reasonable for you

- PHX gets means of concs and then logtransforms it to prepare for regression analysis

- PK gets logs and then calculates means for that logs to prepare for regression analysis

what do you think?
