   ABSTRACT. Attempt to develop a distinct technique for the prediction of duststorm or duststorm followed by thundershower during pre-monsoon season over Gwalior, has been made, Two mean 0000 UTC tephigrams have been produced for the days when the duststorms and thunderstorms occurred. Difference is highlighted in the 0000 UTC surface and TEMP data on the days of duststorm/duststorm followed by thundershower with those on the days of thunderstorm. Statistical analysis of the duststorm data over Gwalior has also been carried out with respect to direction, time, fortnight and month of  occurrence of the event. For prediction of peak gust speed (PGS) of squall due to duststorm a single regression equation has been developed.

The study was conducted to evaluate the groundwater quality along the Kopargaon taluka. Thirty six ground water samples were collected from different sources in pre monsoon and post monsoon season, during the year 2013. The descriptive statistical analysis was carried out besides Pearson correlation. Correlation analysis revealed that very strong correlation exists between HCO3and Na(0.961), HCO3and Mg++ (0.935), HCO3and EC (0.927). Where highly negative correlation is observed between Na and pH (-0.537) during pre-monsoon season. During post monsoon season highly positive correlation is observed between Cl- and Ca++ (0.973), Ca and EC (0.967), Cl- and EC (0.966), SO4 and EC (0.948). Where, highly negative correlation is observed between Ca and pH (-0.533).

INTRODUCTION Stature is the important parameter along with age, sex and race while identifying bodies. Stature has direct relationship with the skeletal dimensions most importantly with lower limbs. This study attempts to derive regression equation (RE) and multiplication factor (MF) from femur length (FL) which could be used for stature reconstruction. MATERIAL AND METHODS The study was conducted amongst the 160 students and staff of Dhulikhel Hospital, Nepal for the period of six months from February 2020 to July 2020. The sample was composed of 95 males and 65 females between the age of 18 - 40 years. The femoral length and height was measured in standard position using standard measuring instruments. Statistical analysis was done using SPSS 25.   RESULTS The mean height and femur length of overall sample was 162.33 ±7.62 cm and 40.14 ±2.132 cm respectively, male surpassing the female dimensions. There was a strong correlation between femur length and stature (r = 0.723, 0.869 and 0.791 for males, females, and overall participants respectively). MF was derived as 4.084 ±0.139, 3.99 ±0.11, 4.047 ±0.135 and RE was derived as y = 75.51 + 2.13*FL ±4.06, y = 55.238 + 2.581*FL ±2.999, y = 48.791 + 2.829*FL ±4.672 for males, females and overall participants. Both methods were checked for accuracy and could successfully interpret the height (p>0.05). CONCLUSION The femoral length was found to be a reliable estimator of stature of an individual by using both RE and MF.

The proposed study investigates the seasonal variation in the concentration and the source of the heavy metals like Mn, Cu, Pb, Zn and Fe in the groundwater samples of Pondicherry region. The study results reveal that, the heavy metal concentration is high during South West Monsoon season (SWM) compared to that of North East Monsoon season (NEM). The pH was near neutral and metal load representing most of the samples were low during NEM. Statistical analysis shows that the 63.7 % of the total variance is observed during NEM and 68.9% during SWM. Geographic information system (GIS) tool was considered for the study to understand the environmental pollution status of the groundwater systems of the study area and to identify the groundwater quality parameters. The multivariate statistical analysis explains that the source of trace metal in the groundwater is derived from natural origin except copper and lead as these contaminants were derived from anthropogenic activities. Based on the output of WATEQ4F, several species of heavy metals exist, in which the dominant species are Mn, CuCl2, PbCO3, Fe and Zn.

The results of recent work at this station regarding the organoleptic grade of cod and haddock and the trimethylamine content of these fish were subjected to statistical treatment. It was established that there is a relation between grade and trimethylamine content which may be represented by a linear regression equation, if the trimethylamine content is expressed as log (1 + TMA value). The confidence with which this TMA index may be used to estimate grade was also determined. Based on these findings, a scale of TMA values for use in practical grading was set up; the suggested values are grade I: TMA value 0.00 to 1.00; grade II: TMA value 1.01 to 7.00 and grade III: TMA value 7.01 and higher. Finally, a method is suggested by means of which the ability of a grader to judge the quality of fish may be assessed.

The objective of this study is to examines competency on budget qualities. As well as to search an regulation, and it may modernize the influence of competency on budget qualities. In practice, the results of this study contribute for local parliamentarian and local government when they prepare the budget. This study used 70 respondency that being collected from 19 Unit Managerial District in Padang. The statistical analysis is based on single regression analysis to test first hypothesis and interaction analysis or moderated regression analysis (MRA) was used for analysis second hypothesis. The results show that competency have significant effects on budget qualities. Moderated regression analysis result indicates that the regulation may not lead modernization competency on budget qualities. Based on this results and framework for identifiying moderator variables, this research conclude that regulation is not as moderator variable on relation between competency and budget qualities.

Abstract This chapter focuses on regression diagnostics. The development of a regression equation is only the first half of a regression analysis. The second, often overlooked part of a regression analysis is to make sure the assumptions underlying the analysis have been met. This is easily accomplished using the regression diagnostic procedures available in SAS® (Statistical Analysis System). Price per flat of strawberries and their availability on the open market were used as an example.
