Nowadays, the impacts of climate change are harming many countries around the world. For this reason, the scientific community is interested in improving methods to forecast weather events, so it is possible to avoid people from being injured. One important thing in the development of time series forecasting methods is to consider the set of values over time that facilitates the prediction of future value. In this sense, we propose a new feature vector based on the correlation and autocorrelation functions. These measures reflect how the observations of a time series are related to each other. Then, univariate forecasting is performed using Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM) deep neural network. Finally, we compared the new model with linear and non-linear models. Reported results exhibit that MLP and LSTM models using the proposed feature vector, they show pro...

En el esquema de metas explícitas de inflación y regímenes relacionados, la identificación de la inflación transitoria y las proyecciones de inflación constituyen ingredientes claves para tomar decisiones de política monetaria. Por ello, en la práctica, los bancos centrales usan medidas de inflación subyacente. Este documento construye medidas de inflación subyacente basadas en funciones wavelet y en análisis multi resolución (MRA) para luego evaluar su relevancia para la política monetaria. La construcción de medidas subyacentes con wavelets (WIMS) es relativamente nueva en la literatura y su evaluación no ha sido formalmente realizada, este documento es el primer intento de materializar ambas tareas para el caso del Perú. La otra contribución del documento es la propuesta de dos métodos para evaluar una medida de inflación subyacente: (1) un criterio de largo plazo b...

“The objective of the research was to evaluate the consistency of different training proposals, proposing as a reference a competency-based curriculum planning model. Qualitative methodology was used from an interpretive paradigm, making use of inductive and deductive analysis at the same time. Inductively, observations were generated through documentary analysis, interviews with experts, and a focus group with university professors, who then deductively derived interpretations and forecasts regarding curricular planning. As a result, it was obtained that the designed model, based on the triangulation of the information collected, allowed evaluating and determining the strengths and weaknesses of the priority elements of the university curriculum: the graduation profile, the study plan and the evaluation system. The main conclusion was that it is necessary to have clear parameters for ...

The study proposed an inventory policy for its products with the highest demand based on the analysis of the application of three planning techniques, which were the Silver Meal method, the minimum unit cost method and the EOQ. In addition, forecasting techniques were applied with a bimonthly historical data from the sales record that helped identify the products with the highest demand according to the ABC classification. The methodology carried out in a grocery store in Peru found that the demand behavior differed in each product; so, the standard deviation was analyzed. Then, the application of the three planning techniques was compared where a similarity in the frequency of orders and quantity between the Silver Meal and MCU was observed; on the other hand, the EOQ functioned as a preliminary step to identify a reorder point.

For this purpose, a characterization of the behavior of the pandemic was carried out in the first three months of its development, based on the analysis of trends and the determination of the effective reproduction number (Rt) from statistical-mathematical methods. A variant of the SIR mathematical model was applied to forecast the possible evolution of the pandemic. This model was adjusted with the GlobalSearch optimization strategy of the MATLAB software. His solution used the MATLAB function ode23tb, which uses a combined Runge-Kutta algorithm with a trapezoidal rule algorithm. With the application of the Kaizen strategy as a means of continuous improvement, a set of actions were proposed that could be carried out today and t...

The demand for long and short term real balances for Peru is theoretically consistent and empirically robust using the seasonal cointegration methodology. The stability of this function is of paramount importance for the management of monetary policy. The study uses quarterly data for the period from the fourth quarter of 1991 to the first quarter of 2014; considers a demand for money based on a scale variable representative of the income of the economy, interest rate in national currency and nominal exchange rate. The coefficients of income elasticity, interest rate and exchange rate vary in sign and magnitude depending on the theory. The long-term model and the mechanism of error correction using the short-term models exceed statistical tests, whereas the chow and cusum squared tests explain that the demand for money is a stable function. The exogeneity analysis of the regressors shows...
