Table S2/ bark thickness calculations #143

Closed teixeirak closed 4 years ago

teixeirak commented 4 years ago

@mcgregorian1 ,

I'm taking a pass through the methods and have a question on this: "Specifically, we used linear regression on log-transformed data to relate $r{bark}$ to diameter inside bark from 2008 data (Table S2), which were then used to determine $r{bark}$ in the $DBH$ reconstruction. ". I actually deleted the sentence because I don't think its essential and we need to cut, but we should be specific about this in Table S2. If the equations are indeed based on diameter inside the bark, we need to specify that.

Further, I'm noticing inconsistency of bark thickness symbol between text and table S2. I'll fix that.

further, we need to specify units for r_bark and DBH in the header to this table

same goes for Fig. 3-- need to specify units.

Based on the steps I have written in the code, I think your first point about the methods is correct (these are the first three out of a total of 7).

  1. Calculate diameter_nobark for 2008 = DBH.mm.2008-2*bark.depth.mm
  2. log-transform both diam_nobark_2008 (x) and bark.depth.mm (y)
  3. Fit a linear model, and use model to predict log(bark.depth.mm)

I've updated the table - let me know what you think.

same goes for Fig. 3-- need to specify units.

I'm not sure what you mean? Rt and Rs are unitless measurements.

Sorry, I meant Table S3. I've updated the table heading to include the units.
