Cho 1 Statistic Literature Review – OLS Regression
1. A brief summary of the statistical method (1) What is the method? Regression is a statistical technique used for modeling and analysis of numerical data by finding the best-fitting straight line. In other words, a regression line is defined the combination between the average values of a numerical outcome variable and deterministic variables. The ways to find a best fitting straight line, es...
متن کاملStereochemistry of the myo-inositol-1-phosphate synthase reaction.
Experiments with D-glucose-6-P stereospecifically tritiated at C-6 showed that the myo-inositol-1 P synthase reaction catalyzed by both the enzyme from beef testis and from pollen of Lilium longiflorum proceeds with stereospecific loss of the pro-6R and incorporation of the pro-6S hydrogen into the product. The ring closure thus occurs in a retention mode at C-6 of the substrate, a finding at v...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Absolute Stereochemistry of the Diepoxins
The exciton coupled CD method has been applied to determine the absolute configuration of the diepoxins, spiroketaI-linked naphthodiepoxydecaIinones of fungal origin. The CD spectra of the bis-dimethylaminobenzoate derivatives of the diepoxins 71, land ~c, reveal a positive chiral twist between the two substituted hydroxyl groups and thus infer the $ configuration at both of these stereogenic c...
متن کاملThe stereochemistry of betulaprenol biosynthesis.
By using stereospecifically double-labelled radioactive mevalonates it was shown that betulaprenols-6 to -9, found in the woody tissue of Betula verrucosa, each contain three biogenetically trans-isoprene residues and that the remaining residues are biogenetically cis. The results obtained with these radioactive mevalonates also indicated that the activity of isopentenyl pyrophosphate isomerase...
