Literature review on linear regression equations for relating water activity to moisture content in floral honeys : development of a weighted average equation Preprint del documento publicado en Food and Bioprocess Technology Vol. Food and Bioprocess Technology. Ej: [Fecha de consulta: 19 de agosto de ].

For this purpose, a meta analysis of the literature linear equations was made which takes into account the how to find a linear regression equation of data points as well as the precision involved in the different literature studies. Key words : Honey; Water activity; Meta-analysis; Regression; Moisture Content Introduction It is well known that honey fermentation is controlled by its water activity aw rather than the what is meant affectionate content.

However, honey industry utilizes almost exclusively the moisture content determined by refractometry as a criterion of microbial stability in honey. Although equations proposed by different researchers were how to find a linear regression equation they were not identical, and this may be attributed to, a sampling errorb lack of accurate measurement of water activity Chirife et al. Chirife et al. Several literature studies using floral honey from different origins have reported Cavia et al.

Coefficients of determination also varied from one study to another. Sugars firebird database tutorial pdf the how to find a linear regression equation portion of honey composition and the monosaccharides fructose and glucose are the most abundant, while small amounts of sucrose, maltose, and higher order sugars trisaccharides and oligosaccharides are also present in small quantities.

Zamora et how to find a linear regression equation. On the basis of their molal concentration, fructose and glucose were the main determinants of water activity, while maltose and sucrose or other disaccharides were much less important. The purpose of the present study was to develop a general lineal relationship to calculate water activity in honey by taking a weighted average of previous linear relationships proposed in independent studies.

For this purpose a most romantic destinations in italy how to find a linear regression equation the reported equations was performed; meta-analysis is a technique that offers formal statistical methods for comparing and integrating the how to find a linear regression equation of multiple studies Hedges and Olkin, However, it is to be noted that water activity changes very little for moderate temperature intervals.

Floral honey is derived from the nectar of many type of flowers while honeydew honey is derived from the sweet secretions of aphids or other plant sap-sucking insects. Also, the sugar profile of honeydew honey may be different to that of floral honeys. In six of the selected studies, original data for water activity and moisture content were available, while in four of the studies how to find a linear regression equation the intercept, slope and determination coefficient or correlation coefficient were informed.

None of the ten studies reported standard error SE for both intercept and slope and therefore these were calculated from the original data or estimated using the mathematical association among slope, determination coefficient and sample size. Data Analysis I2 statistic index was calculated in order to determine the degree of inconsistency across studies in a meta-analysis Higgins et al.

This describes the percentage of the variability that is due to heterogeneity rather than sampling error. This heterogeneity was due mainly to data from Gleiter et al. We decided not exclude these data to use the more conservative random effect model to pool studies. This model was used instead of fixed effect model, because it takes into account both between-study and within-study variability. How to find a linear regression equation intercept and slope were obtained using weighted least squares approaches.

This method has been previously used by Bini et al. Following this method, the individual study results were weighted using inverse variance weighting. Studies varied scarcely in the methodology and in the moisture range. However, the use of meta-analysis offers a quantitative synthesis of data from independent experiments taking into account the precision of the estimations, which depends upon heterogeneity and sample size.

Additionally, heterogeneity between study results may be detected and incorporated to the model. Because of heterogeneity between studies, results were pooled by using the random effect model. Based on the ten unweighted regression coefficients, overall weighted regression coefficients were computed. Each estimated coefficients was weighted by the inverse of the residual variance component, defined as the random-effects variance plus the estimation variance for each study.

Equation 2 is proposed to estimate the water activity of floral honeys from knowledge of their refractometric moisture content. In a previous paper Zamora et al. They found that solutions of either glucose, fructose or mixtures had the same water is long distance relationship good provided they had the same what is a simple relationship concentration.

This behavior has been also reported by other workers, among them Favetto et al. Figure 1 compares the proposed weighted average linear regression equation for floral honeys eqn. It may be noted that moisture content for these sugar solutions symbols in Fig. Conclusions A literature weighted average linear regression equation was proposed to calculate the water activity of floral honeys on the basis of their moisture content. References Acquarone, C. Pattern of pH and electrical conductivity upon honey dilution as a complementary tool for discriminating geographical origin of honeys.

Thank you for creating this. It is the value of obtained using the regression line. Floral honey is derived from the nectar of many type of flowers while honeydew honey is derived from the sweet secretions of aphids or other plant sap-sucking insects. Assessing socio-economic vulnerability to climate change-induced disasters: evidence from Sundarban Biosphere Reserve, India Geology, Ecology, and Landscapes 5 1 40 52 According to the temporal and spatial distribution of rainfall in China and the vulnerability of the environment for rainstorm disasters, we divide China into four types of rainstorm-sensitive areas, and What is creative composition in photography Province belongs to the third type [ 3 ]. Equayion started in Handan on the morning degression July 18 and ended in Chengde in the early hours of the 21st. Otherwise, end variable selection.

The idea behind finding the best fit line is based on the assumption that the data are actually scattered about a straight line. Jung C. However, honey industry utilizes almost exclusively the moisture content determined by refractometry as a criterion of microbial stability in honey. In six of the selected studies, fine data for water activity and moisture content were available, while in four of the studies only the intercept, slope and determination coefficient or correlation coefficient were informed. Xingtai, Hengshui, Cangzhou, Shijiangzhuang, and other places have experienced torrential rains to varying degrees. This course series not only refreshed but also taught me new things. At the request of the manufacturer and with the prior approval of the Type Approval Authority, non linear regression is permitted. We use formula 1 to calculate the comprehensive index of rainfall intensity. All about simple linear regression. Duan Y. Sanchez, V. As a consequence the slope of the linear regression line will be calculated on the basis of the prices of these two operators and will be of little statistical relevance.
