This study intensively examined the monthly water consumption forecasting performance using advanced time series (ARIMA) models. Thus, this intends to identify appropriate ARIMA models best fit data in Southwestern Ethiopia Tepi town and forecast effectively city. The used for was from January 2016 December 2021.The were converted returns enhance their statistical properties a mean equation. av...
The traditional approach by Fama and Macbeth (1973) to the validity of an asset pricing model suffers from two drawbacks. Firstly, it uses ordinary least squares (OLS) method, which is sensitive outliers, estimate time-series beta. Secondly, takes averages slope coefficients cross-sectional regressions ignore importance properties. In this article, robust estimators a longitudinal are applied a...
This letter considers the problem of linear time-invariant (LTI) system identification using input/output data. Recent work has provided non-asymptotic results on partially observed LTI a single trajectory but is only suitable for stable systems. We provide finite-time analysis learning Markov parameters based ordinary least-squares (OLS) estimator multiple trajectories, which covers both and u...
The Weibull distribution is regarded as among the finest in family of failure distributions. One most commonly used parameters (WD) ordinary least squares (OLS) technique, which useful reliability and lifetime modeling. In this study, we propose an approach based on multilayer perceptron (MLP) neural network called OLSMLP that resilience OLS method. MLP solves problem heteroscedasticity distort...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
this study was an attempt to investigate the effect of teaching meta cognitive strategies on iranian intermediate efl students speaking proficiency. in this study the researcher has employed metacognitive strategies taken from brown (2000) to teach speaking strategies to number of participants. the participants were intermediate students of shokouh language institute; they were divided into an ...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
This paper provides some small sample evidence on the appropriateness of ordinary least squares (OLS) and instrumental variable (IV) estimators of the structural equation, and on the appropriate method of performing hypothesis testing in event studies when generated variables are present. In event studies, the number of observations used to estimate the auxiliary equations (and compute the gene...
Several efforts have been made to solve the multicollinearity problem, which arises from correlated regressors in linear regression model. This is because Ordinary Least Squares (OLS) Estimator becomes inefficient presence of multicollinearity.
