population in the measurement period; and
 (ii) the variables can be estimated for the entire measurement period and for time periods in the measurement period that are contiguous and do not overlap; and
 (b) the change in the number of sites for which there is data about measured energy consumption, that is used for the purposes of this Part, must, as closely as is possible, be the same for each time period.
 (3) The regression model used for the purposes of subsection (1) must:
 (a) be a least squares regression model; and
 (b) be weighted by the number of days in the measurement period for which there is data, about measured energy consumption at the site, that is used for the purposes of this Part; and
 (c) use data for all sites that are in the control group or treatment group in the population in the relevant pre‑treatment period and the measurement period, unless this determination specifies otherwise; and
 (d) relate average daily emissions of greenhouse gas for the site in the measurement period to several independent variables; and
 (e) include an independent variable that captures whether the site is in the treatment group; and
 (f) include an independent variable that captures mean daily emissions of greenhouse gas in the relevant pre‑treatment period.
