Extended Data Table 3 Estimated learning model coefficients from alternative model 2, which includes an additional covariate for cumulative national installed capacity

From: Quantifying the cost savings of global solar photovoltaic supply chains

  1. Alternative model 2 considers adding cumulative national installed capacity (cum_installed_kw_i) into the model. This table shows that the nation-specific installed capacity terms are not statistically significant. Furthermore, the primary coefficient of interest, βi, is very close to those in our main regression model (see Extended Data Table 1). Asterisks indicate the level of significance: *5%, **1%, ***0.1%.
