Variance

validity of brand loyalty measurement scale. Based on the output of SPSS (details in Appendix F), we observed that there are three main steps to examine the validity. First, looking at the values of KMO and Bartlett's Test. Then, based on the Total Variance Explained table to determine the numbers of extracted factors. In the end, based on the Rotated Component Matrix table to observe the value of each variable factor loadings (a rule of thumb that factor loadings should greater than 0.30) to…

material variance in either positive or negative ways. If the company has tendency to save money from buying lower quality of material purchases than the standard, it will result in adverse direct…

adding a variance delay to reorder the packets. I added 75ms of a variance delay to both throughputs. The following is the totaltraffic graph of both. Figure 16: Server of 4KB and 250ms with 75ms variance Figure 17: Client of 4KB and 250ms with 75ms variance Figure 18: Server of 32KB and 50ms with 75ms variance Figure 19: Client of 32KB and 50ms with 75ms variance Case 4. In comparing the…

After the data was collected it was formulated into 4 tables relating to Alpha Amplitude, Alpha Frequency, Beta Amplitude and Beta Frequency, the tables can be found in the appendix section below. The tables contain ID numbers to identify the volunteers as well as columns to show the amplitude (μV)/frequency (Hz) of alpha and beta during the four periods of no music (NM1, NM2, NM3, NM4),CL, CH, RL and RH. The percentage increase for all the different types of music compared to no music was…

should sum to 100%. A baseline technology should be selected with which to compare all the other technologies or solutions. A variance factor between the baseline and the alternative is assigned and put in the appropriate cell. Commonly -9, -3, -1, 0, 1, 3, 9 are the assigned variance levels. The assigned variance levels can be biased and should be scrutinized. The variances and weight factors are multiplied and added together to obtain a total comparison against the baseline technology or…

intention was .44. A non-significant weighted average correlation (r= .30) was observed between PBC and intention. TPB constructs predicted 30% variance in intention. Inclusion of AR predicted an additional 7% of variance in intention. The inclusion of past behaviour resulted in a further increase of 6% in variance. Intention alone accounted for 16% variance in behaviour. PBC was found non-significant predictor the…

in earlier works of Harry Markowitz (1952, 1959) and Roy (1952). According to Markowitz (1952), risk can be eliminated through diversification by spreading the wealth across the assets. In his work, Markowitz (1959) implemented the theory of mean-variance of market portfolio which provided the initial foundation for capital asset pricing model. His model was a static model which assumed that investors tend to invest in a portfolio at time t-1, and gave stochastic return in the period t. One of…

rerun the EFA with the PCA. When examining the interAs examined the variance explained by each factor (see Table 4), Factor 1 accounts for 20.8 % of the total variance; Factor 2 accounts for 15.2% of the total variance; Factors 3 accounts for 12.9% of the total variance; and, Factor 4 accounts for 9.8 % of the total variance in the items after rotation. Also note that four-factor solution has accounted for 58.84 % of the total variance (15.298766/26 = 0.5884). Finally, the matrix of inter-factor…

Although the elegant Black-Scholes’ theory is, there is an absolute disadvantage(Heston 1993). The strong assumption of constant volatility cannot express high peak and flat tail character of derivatives, and the relative between the spot return and the variance. Therefore, there are several theories try to extend and modify the original Black-Scholes’ model. The Heston stochastic volatility model is the most popular extension to the Black-Scholes’ model(Tse & Wan 2013). The first scheme widely…

4. IMPACT OF SPEED ON CRASHES 4.1 Speed variance vs crashes Solomon (1964) describe the effect of speed vs crashes as a U shaped curve [9]. Solomon obtained the estimated speed of the vehicles suffered the crashes by tracing the police reports. The author compiled a “modus speed” which implies a safe speed for that particular stretch of road by driving with the traffic flow [45]. Solomon created a crash proportion per speed category, a comparison ratio using the crash vehicle speeds and the…
