In fisheries science, high number of morphometric measures (independent variables) taken from different parts of the fish complicates the estimation of the body weight (dependent variable). Therefore, the researchers are seeking for a solution facilitating the interpretation of the equations of correlation between the characteristics. One way to deal with this challenge is the dimension reduction by means of stepwise multiple regression analysis. The aim of this study is to explain total variation with the same accuracy by using fewer independent variables. To accomplish this, 12 morphometric measures from 210 individuals of Serranus cabrilla were measured to estimate the body weight. Firstly, the 95% of the variation was explained by means of multiple regression analysis by using all variables. Then, by step-wise method, the same results were achieved with fewer independent variables. Finally, the variables with inter-multicollinearity eliminated and with two remaining independent variables determination coefficients resulted as 95%. The result showed that using more variables does not create significant distinction for accuracy to estimate the body weight although; the total length and body dept was the most effective features for weight.

This study aimed to determine the Correlation and the regression equation between body measurements and body weight of Brahman Cross (BX) Cow in KPT Maju Sejahtera Trimulyo village, Tanjung Bintang District, Lampung Selatan Regency. This research was conducted in July 2020. The data obtained were analyzed using simple and multiple regression analysis using the help of the Excel program. The material used in this study were 32 Brahman Cross (BX) Cow aged 2-3 years. The results of this study indicated that the average of Body Weight (BW), Chest Circumference (CC), Body Length (BL), and Shoulder height (SH) were 472.66 � 53.59 kg, 179.95 � 7, 95 cm, 132.49 � 6.39 cm, 127.95 � 3.08 cm, respectively. The correlation value between CC, BL, SH with BB were 0.764, 0.448, and 0.551, respectively. These results indicated that CC, BL, SH, have a positive relationship with BW. The regression equation resulting from the relationship between body weight and body size CC, BL, SH to BW with the value of determination (R2) and significance (P?0.05) was 0.607 (60.7%) with the regression equation BW = -674.003 + 4.314 CC + 1.247 BL + 1.602 SH. Keywords: Brahman Cross, Body Measurement, Correlation and Regression

The relationship between heart girth, wither height, body length and body weight in 3- to 9.5-month-old pre-pubertal Finnish Ayrshire heifers gaining 600-650 g/d was analysed (experiment I). Regression analysis showed that heart girth was the trait most highly correlated to body weight (R2 = 0.969). Including body length or wither height as a second term in the regression, increased R2 values only slightly. When the relationship between heart girth and body weight was used to predict the body weight of heifers reared at two feeding levels (experiment II), the precision of prediction was affected by the plane of nutrition. Actual body weight for a given heart girth was slightly higher on the high than on the low feeding level. It is, nevertheless, concluded that the equations presented in the paper can be used to estimate accurately the body weight of pre-pubertal (95-140-cm heart girth) Ayrshire heifers gaining 550-700 g/d.

Purpose: This research aims to study the relationship between perception of elderly’s health and health behaviors in Nakhon Nayok province, Thailand Methods: This research was a cross-sectional study. The questionnaire was used to collect the data. This research was conducted in Nakhon Nayok province. The sample size was 270 which applied Taro Yamane's formula at a significant level 0.05. The descriptive statistics was implemented to describe the variables by presenting the frequency, percentage, mean and standard deviation. Furthermore, multiple regression analysis was applied to analyze the relationship between perception of elderly’s health and health behaviors. The statistical significance was considered to reject Hypothesis-null at < 0.05. Results: From a total of 270 people, more than 58.22% of the elderly perceived that they had moderate health conditions. Most elderly had congenital diseases (62.2%). The multiple regression analysis results showed that health status perception and health status perception when compared to their cohort related significantly to health behavior. Conclusion: The government should support the elderly on participation, trust, engagement, and cultural concern of the people in the community, which can contribute to promoting the physical, mental and social condition of the elderly.

The relations of the Strepsipterous parasite Halictophagus pontifex Fox to seven species of its Cercopid (Aphrophorinae) hosts were studied at a grassland site in Uganda. Dissections of weekly samples of the Cercopids collected by sweeping showed that the duration of the life-cycle of H. pontifex is 30–40 days. The parasite is found only in adult hosts which can support as many individuals (up to 7) in Poophilus costalis (Wlk.) as can develop in the space available in the body cavity. Both the maximum number of parasites per host and the rate of parasitism are related to the volume of the host. Parasitism arrests development of the ovaries of female hosts; they may reproduce after emergence of male parasites but not after exhaustion of females because of reinfection by triungulins. Graphical and regression analysis of the population data (no. individuals/1 000 sweeps) show that, for P. costalis, parasitism by H. pontifex is density dependent and the chief regulating factor. Rainfall 58–64 days before sampling also was correlated with P. costalis density, but multiple regression analysis showed it to be insignificant.

Total suspended solid (TSS) is one of the parameters that determines whether or not a body of water is polluted. One factor that influences the amount of TSS content is the characteristic of rainfall in an area. Purpose of this study was to determine the relationship between the effect of rainfall characteristics and TSS content in Ciliwung River. Multiple regression analysis was used for analytical method.  Results of multiple regression analysis showed that the correlation coefficient (adjusted R2) for the factors of rainfall, discharge and sediment show a low correlation to changes the content of TSS in Ciliwung River. The value of each correlation coefficient in the upstream, middle, and downstream of Ciliwung River are 0.21, 0.31, and 0.09 respectively. According to the F test, rainfall, discharge and sediment  were significantly affect TSS content in the upstream and middle stream.  Based on t test, it is known that only rainfall affect TSS content in the upstream and midlle stream.

Using a special questionnaire adapted for computer evaluation, the prevalence of signs and symptoms of craniomandibular disorders (CMD) and occlusal disharmonies was investigated in a group of 500 adolescents of the Republic of Serbia ranging between 18 and 25 years of age. The presence of signs (symptoms) of CMD and occlusal discrepancies was established using clinical exsamination and evaluated according to the clinical disfunction index (D i) and index of the occlusal state (Oi) proposed by Helkimo et al. 1974. The results of this study revealed that 327 (65.4%) adolescents in the examined group had at least one sign (symptom) of CMD, (Di > 1), and that 271 (54.2%) adolescent had also mild, or severe occlusal discrepancies (Oi > 1). The percentage of persons with signs(symptoms) of CMD was significantly greater in the group having occlusal discrepancies (X = 7.76, P<0.01). The multiple regression analysis of the obtained data and the ODDS ratio confirmed the risk of CMD in the group with occlusal discrepancies to be 2.5 times greater than in the group of adolescents without occlusal discrepancies.

This chapter integrates collectivism with the dimensions of the Expectancy Theory to investigate the direct and indirect impact of horizontal and vertical collectivism on employee motivation of operational and non-operational staff. Data were collected from 205 employees using a cross-sectional survey. Hypotheses were tested with multiple regression analysis. Across both employee categories, horizontal collectivism improves motivation while vertical collectivism does not have a significant impact on motivation. Mediation effects were significant in the relationship between horizontal collectivism across both employee categories. However, there were some variations in the mediation effects on the relationship between vertical collaboration and motivation across the two categories. This chapter contributes to motivation literature by integrating the Expectancy Theory with two under-investigated dimensions of collectivism to compare motivation determinants among operational and non-operational staff. This chapter presents implications for managers and policy for improving employee motivation.
