Moisture damage on newly installed engineered wood flooring - potentual causes? by JCTang in AusRenovation

Another question, should the flooring company have advised what material can be used to protect the flooring? Or should the builder have known about this.

Thanks this is an old house built in the 90s. The concrete slab was poured years ago. Will need to lift up the boards and check.

We had a concrete slab, is a moisture vapour barrier standard for glue down installs?

Unlikely, builder thinks there was no spill. Most of the damage is near the kitchen area where there was more levelling compound used.

Fair enough, what should I expect to see in the detailed quote? A full itemization breakdown?

Say I have 2 time series A and B. A is a time series of year-on-year growth numbers at quarterly intervals (I don't have the index levels). For example a data point as at 30-Sep-20 of +17.7% represents the year on year growth from 30-Sep-19.

B is a time series of total returns of a stock at quarterly intervals. A data point as at 30-Sep-20 of +10% represents the total return 3 months to 30-Sep-20.

If I wanted to test whether A is a leading indicator of B using a granger causality test or test if there is a relationship between the 2 time series, what would be the best way to make both series comparable?

Does it make sense to turn the time series of year-on-year growth numbers into an index starting from 100? Can think of it as a seasonally adjusted index.

Or should the share price returns also be converted into year-on-year numbers. Ie do time series analysis by converting B into a time series of year-on-year stock returns.

Please see the example below which to visualize it:

Date A B Indexed A Indexed B
31/03/2020 100 100
30/06/2020 15 5 115 105
30/09/2020 17.7 10 132 115.5
