This paper presents an approach to estimate demand in the Polish Power System (PPS) using the historical electricity usage of 27 thousand commercial customers, observed between 2016 and 2020. The customer data were clustered and samples as well as fe

Nearly 60% of commercial customers are connected to a low-voltage network in Poland with a contractual capacity of more than 40 kW and are assigned a fixed tariff with flat prices for the whole year, no matter the usage volume. With smart meters, mor

We consider kernel density estimation in the multivariate case, focusing on the use of some elements of parametric estimation. We present a two-step method, based on a modification of the EM algorithm and the generalized kernel density estimator, and

The paper aims at analysing errors in the National Inventory Reports, provided annually since 2001 by parties to the UNFCCC. Each said report contains the data on GHG emission from a given year and revisions of past data (back to 1990), recalculated

This paper addresses the problem of learning in greenhouse gas (GHG) emission inventories understood as reductions in uncertainty, i.e., inaccuracy and/or imprecision, over time. We analyze the National Inventory Reports (NIRs) submitted annually to

We consider a discrete-time non-stationary stochastic process being a sum of two other processes. Given a data matrix of its realizations, we aim to estimate and then analyze the mean values of the component processes as functions of time. Both exist

In this paper we use density estimation to investigate the particle size distribution in surface water and to extract the components of density functions obtained. This distribution helps to investigate quality of water with respect to its physical c
