Abstract:
In this thesis, an analysis of Bitcoin, Monero price and volatility is conducted with respect to S&P500 and the VIX index. Moreover using Python, we computed correlation coefficients of nine cryptocurrencies with two different approaches: Pearson and Spearman from July 2016 -July 2018. Moreover the Pearson correlation coefficient was computed for each year from July2016 - July 2017 - July 2018. It has been concluded that in 2016 the correlation between the selected cryptocurrencies was very weak - almost none, but in 2017 the correlation increased and became moderate positive. In 2018, alm

ABSTRACT ROBUSTNESS OF TWO FORMULAS TO CORRECT PEARSON CORRELATION FOR RESTRICTION OF RANGE by Dung Minh Tran Many research studies involving Pearson correlations are conducted in settings where one of the two variables has a restricted range in the sample. For example, this situation occurs when tests are used for selecting candidates for employment or university admission. Often after selection, there is interest in correlating the selection variable, which has a restricted range, to a criterion variable. The focus of this research was to compare Alexander, Alliger, and Hanges’s (1984) formu

Abstract:
Esta dissertação de mestrado apresenta os resultados de uma investigação sobre os métodos de co-estimativa comumente utilizados em geoestatística. Estes métodos são: cokrigagem ordinária; cokrigagem colocalizada e krigagem com deriva externa. Além disso, a krigagem ordinária foi considerada apenas a título de ilustração como esse método trabalha quando a variável primária estiver pobremente amostrada. Como sabemos, os métodos de co-estimativa dependem de uma variável secundária amostrada sobre o domínio a ser estimado. Adicionalmente, esta variável deveria apresentar correlação linear com a va

Abstract:
Most American universities and colleges require students to provide faculty evaluation at end of each academic term, as a way of measuring faculty teaching performance. Although some analysts think that this kind of evaluation does not necessarily provide a good measurement of teaching effectiveness, there is a growing agreement in the academic world about its reliability. This study attempts to find any strong statistical evidence supporting faculty evaluation by students as a measure of faculty teaching effectiveness. Emphasis will be on analyzing relationships between instructor ratings by

This thesis deals with speech analysis of people who suffer from Parkinson’s disease. Purpose of this thesis is to obtain statistical sample of speech parameters which helps to determine if examined person is suffering from Parkinson’s disease. Statistical sample is based on hypokinetic dysarthria detection. For speech signal pre-processing DC-offset removal and pre-emphasis are used. The next step is to divide signal into frames. Phonation parameters, MFCC and PLP coefficients are used for characterization of framed speech signal. After parametrization the speech signal can be analyzed by sta

Climate data are very useful in many fields of the scientific research. Nowadays, in many cases these data are available through giant data-base that are often yielded by automatic meteorological networks. In order to make possible research analysis and the running of computational models, these data base need to be validated, homogenized, and to be without missing values. Validation and homogenization are common operations, nowadays: the organizations that manage these data-base provide these services. The main problem remain the reconstruction of the missing data.

碩士<br>國立清華大學<br>統計學研究所<br>104<br>This thesis aims to develop the varying local correlation function of two variables $X$ and $Y$ given another variable $T$ in a neighborhood of $t_0$, which can capture the relationships between $X$ and $Y$ among defferent $t_0$'s. In the literature, Bjerve and Doksum (1993) introduced the correlation curve of two variables $X$ and $Y$ given $X$ in a neighborhood of $x_0$, which applies to two variables with a nonliner relationship. First, we reveiw the relationships between the Pearson correlation and the simple linear regression, and extend it to the relation

The research only focuses on the courses in the program of Electrical Engineering at the University of Victoria. Three approaches based on the two major factors, coefficient and enrolment, were established to select the course grade predictor including Max(Pearson Coefficient), Max(Enrolment), and Max(Pi) which is a combination of the two factors.

So far there are many methods have been developed to evaluate evolutionary relationships. However, multiple sequence alignment (MSA) should be performed before those methods. Several studies have shown that the order in which sequences were added to a MSA could significantly affect the end result. Therefore we want to find if there is another method that makes more reliable results. Our goal is to construct a unique and reasonable phylogenetic tree building method bet

On the one hand, wafer lot in some specific process steps with longer cycle time is more likely to be contaminated by particles or oxidized. On the other hand, an abnormal event sometime may result in low yield with longer cycle time. Therefore, cycle time has become either a direct or indirect factor to yield loss. Using cycle time data for yield analysis is a new topic in semiconductor manufacturing. Ther
