    1196 Words  | 5 Pages

    REGRESSION ANALYSIS R-squared is a statistical measure of how close the data are in the fitted regression line. The definition of R-squared is the percentage of the response variable variation that is explained by a linear model. OR R-sequared is always between 0 and 100%; where 0% indicates that none of the variables of the response data around its mean, where as, 100% indicates that all the variability of the response data around its mean. Usually, the higher the R-squared, the better the model

    subsection{Recommending Unexpected Relevant Items} Once the forgotten items have been identified, we need to distinguish relevant ones from the rest. Given user taste shifts, as well as the changes in the system as a whole, not all unexpected items remain relevant, and consequently useful for recommendation. The key concept to identify relevant items is the extbf{relevance score} of the items at each moment. We propose four strategies to define the relevance score of each unexpected item. The goal

  • Sdg's Sustainable Development Goals

    1071 Words  | 5 Pages

    Sustainable development goals are goals that are much more detailed than the Millennium Development Goals. Previously, in the MDG’s there were only 8 goals which seems to be the base line for the SDG’s. The SDG’s are much more all-inclusive, by splitting each of the MDG’s into smaller goals, thus creating 17 goals in total. The SDG’s did not seem to cover all of the issues, while, as the MDG’s does seem to be covering the majority of the global problems. Goal 1: End poverty in all of its forms

    What Are the Advantages of Bilingual Educational Programs and Bilingualism? It is difficult for me to write this from the point of view of an educator in the United States. I am presently at the end of my second year of teaching and also my second year at a totally bilingual school that teaches in both Spanish and English. My opinions and reflections on my literature reviews may be affected by my teaching here in Mexico, vs. teaching ESL students who are immigrants located in the USA. Bilingual

  • Advantages And Disadvantages Of Crime Investigation

    2594 Words  | 11 Pages

    Abstract - Criminalisation is a social phenomenon, which has drastically increased in last few years. In order, to make the job of the investigating agencies easy, use of technology is important. Crime investigation analysis is a field where data mining plays a vital role in terms of predicting and analysing the criminals. In our paper, we have proposed an integrated model for physical crime as well as cybercrime investigation. Our approach makes use of data mining techniques for crime detection

  • Analysis Of Variance (ANOVA)

    Fundamental of Analysis of Variance (ANOVA) According to explanations above about testing of the model, Sterman (2000) presents that the model should be tested in 7. Step using statistical method in order to know the behaviour reproduction of the model. The purpose of that step is to know how the model can reproduce the behaviour of interest in the system. There are many statistical methods can be used for testing the model. In this paper the statistical model used is analysis of variance (ANOVA)

  • Rater Errors

    805 Words  | 4 Pages

    Engelhard (1994) and Saal, Downey and Lahey (1980) stated there are four major categories of rater errors. The first tendency is towards severity and leniency which is a rater consistently giving lower or higher appraisal than a deserved performance. Engelhard (1994) mentions that it should be the best for raters to be continuum severity or leniency, if test takers are scored by raters who have much severity variance. Thus people can get higher scores than they deserve or some may get lower scores

    Suppose we have a single-hop RCS where there is one AF relay that amplifies the signal received from a transmitter and forwards it to a receiver. Assume that the transmitter sends over the transmitter-to-relay channel a data symbol ${s_k}$, from a set of finite modulation alphabet, $S={S_1, S_2,ldots,S_{cal A}}$, where ${cal A}$ denotes the size of the modulation alphabet. The discrete-time baseband equivalent signal received by the relay, $z_k$, at time $k$ is given by egin{equation} z_k = h_{1

  • Keratoconus Case Study

    769 Words  | 4 Pages

    General guidelines for screening for keratoconus: 1. Anterior and posterior elevation maps (Demirbas et al., 1998): In the anterior elevation map differences between the best fit sphere and the corneal contour of less than +12 μm are considered normal, between +12 μm and +15μm are suspicious, and more than +15 μm are typically indicative of keratoconus. Similar numbers about 5 μm higher apply to posterior elevation maps. 2. Anterior curvature map (Tomidokoro et al., 2000): The

  • Importance Of Sex Education In The Philippines

    We have ever been to the streets and noticed a young woman carrying a baby. It’s such a challenge that the woman is facing, the father of the baby, and probably their parents. I always think what if they got acquired an education about sexuality then maybe they would have made a better decision. In the Philippines, sex education is still a hot debate on whether it will be implemented or not. It was opposed by some religious groups, who claimed that sex education encourages teenagers to be sexually

    Having taken the Jung Typology Test, my MBTI results have changed as follows:- From: ESTP E for Extroversion, S for Sensing, T for Thinking and P for Perceiving To: INTP Introvert (9%), iNtuitive (22%), Thinking (9%), and Perceiving (16%) While there is a match with TP preferences, there is a strong deviation in my selection as it applies to the Sensing and iNtuitive preferences. I am not too worried about the change from Extroversion to Introversion as the variation of 9% is not too high. It must

  • Urban Sprawl Essay

    1358 Words  | 6 Pages

    To begin with, we present the results from the parameters of the urban sprawl variables. The percentage of urban area carries a positive sign in the local security and urban infrastructure and a negative sign in all other categories; it is significant only in the administration spending. Continuing, the CV does not seem to be a good measure of urban sprawl, its estimated parameters are insignificant in all the equations; in addition, its sign is negative in most estimation, the opposite of expected

  • Sensory Modulation Analysis

    1545 Words  | 7 Pages Models of sensory modulation Several models relating to sensory modulation are described in the literature. Earlier models approached sensory modulation in a linear manner, ranging from under-responsivity (or failure to orientate) on one end, and over-responsivity on the other end of the continuum.16,33,118 The linear models did not explain the complexity of the process which led to more dynamic models. The Ecological Model of Sensory Modulation (EMSM) views sensory modulation as interlinked

    Spread Ratio The magnitude of p-value indicates that linear terms of all the variables have significant effect at 5% level of significance (p <0.05) on cookie’s spread ratio. Further quadratic effect of fat content was significant effect at 5 % level of significance (p<0.05). The magnitude of β coefficients (Table 3) revealed that the linear term of fat (β= 0.24) and AF (β= 0.087) have positive effect; whereas the SMP (β= -0.037) has negative effect on cookie’s spread ratio, which indicates that
