I think a better answer is it depends. Statisticians will give you an answer that is generally oriented towards theoretically driven and parsimonious insights whereas computer scientists working in a massively parallel environment where there ...
Our dependent variable is the location decision of each gold mining firm using data on mine births. Although we also have data on mine closings, which could also be used as a location indicator of firm sensitivity to environmental regulations, we use the birth of new mines as our dependent variable.
2017-3-28Homestake Mining Company, an iconic name in the history of gold mining in the United States, manufactured gold bars for 122 years, from 1878 until 2000. The gold refinery, established in 1878, was located adjacent to the Homestake Mine in the companys mining town, Lead, about 50 miles 80 km north east of Rapid City in South Dakota.
Indeed the dangers of data mining and p-hacking are a regular theme in statistics literature and on statistics blogs. To get a better gut feeling of the relationship between sample size and possible biases from data mining, I just have run different Monte-Carlo simulations in R that are shown below.
2018-11-22I am evaluating the impact of gold price on the capital structure of 63 gold mining companies from Q1 2003 - Q4 2017. The panel data set is unbalanced because e.g. not all companies reported their Q4 2017. ... I would consider whether a quadratic relationship between one of your predictor and the dependent variable is allowed by your data ...
2014-8-13A typical Oxford University econometrics exam question might take the form Data mining is bad, so mining with more candidate variables than observations must be pernicious. Discuss. Similar questions may well be asked at other academic institutions, but there may be few outside Oxford University where the candidates are expected to refute both myths.

Background. Research on the relationship between mining and sexual and reproductive health SRH is limited, almost exclusively concerned on the HIV spread in mining contexts. Colombia, like other Latin American and Caribbean countries, experienced an unprecedented mining boom since the mid-2000s with insufficient evidence on its effects on SRH.
2009-8-27includes a stochastic connection between the dependent variable of an expression that describes a process and independent variables represented as random quantities. The output will be a probabilistic distribution. The uncertainties in a planned mining operation include Commodity market characteristics, particularly price
2019-11-2How does one use machine learning to identifyanalyze the importance and impact of independent variables on dependent variables Lets say I have a data set with independent variables being carbohydrates, fiber, fat, protein and dependent variable is healthy.Independent variables are linear grams consumed in the past week and healthy is categorical.
Gold-Mining Week 9 2019 Offensive Programming in action part III ... It is a good idea to visually inspect the relationship of each of the predictors with the dependent variable. Generate separate scatterplots with the line of best fit for all the predictors in x with y on the vertical axis. Use a loop to automate the process.
2019-12-20Gold reserves refers to gold in the ground that a mining company has an option to retrieve.. 68 million ounces is a lot And yes, a mining companys value is partially dependent on the size of their reserves. But it costs an exorbitant amount to retrieve gold.
2019-12-24Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their ...
Machine learning regression technique can be used to predict the price of one of the most important precious metal, the Gold. I have created a simple machine learning linear regression model in Python that takes information from the past Gold ETF ...
2016-9-5Regression analysis establishes a relationship between a dependent o r outcome variable and a set of predictors. Regression, as a data mining technique, is supervised learning. ... refer to the mining of gold from rocks or sand, we say gold mining instead of rock or sand mining. Analogously,
The frequency of each pattern is determined in each drug class. An example pattern characterized by 3 attributes is defined in the bottom left. The difference between the experimental groups of interest is then tested using the relative frequency of performing each of the 73 042 patterns as the dependent variable.
2014-6-29variable is the whole building chilled water flow rate during the summer and autumn of 2013. The following sections present the application of some data mining techniques for data prepro-cessing, transformation and mining to select the most appropriate regressors for the future pre-diction of the target variable.

2014-1-15The mining industry in Peru is currently facing a difficult economic environment due to high volatility in metal prices. Currently there are many mining projects, especially in the exploration stage, which find it difficult to fund their different investment stages as investors are unsure of the value the project will generate.
Simple linear regression univariate regression is an important tool for understanding relationships between quantitative data, but it has its limitations. One obvious deficiency is the constraint of one independent variable, limiting models to one factor, such as the effect of the systematic risk of a stock on its expected returns. Real relationships are often much...
