Do you want to calculate probabilistic coherence of topics after the model is trained defaults to true.Calcr2 do you want to calculate r-squared after the model is trained defaults to false.Returnall logical.Do you want the raw results of the underlying function returned along with the formatted results defaults to true.
Read MoreThe degree to which a system has no pattern is known as entropy.A high-entropy source is completely chaotic, is unpredictable, and is called true randomness.
Read MoreWe now need to calculate the terminal value, which accounts for all the future cash flows after this ten year period.The gordon growth formula is used to calculate terminal value at a future annual growth rate equal to the 10-year government bond rate of 0.5.We discount the terminal cash flows to todays value at a cost of equity of 7.9.

Read MoreSimple example.The distance function is implemented using the same logic as rs base functions statsdist and takes a matrix or data.Frame as input.The corresponding matrix or data.Frame should store probability density functions as rows for which distance computations should be performed.
Read MoreIn software testing, a false negative would mean that a test designed to catch something i.E.A virus has failed.In the justice system, a false negative occurs when a guilty suspect is found not guilty and allowed to walk free.False negatives create two problems.The first is a false.

Read MoreWith an enormous amount of data stored in databases and data warehouses, it is increasingly important to develop powerful tools for analysis of such data and mining interesting knowledge from it.Data mining is a process of inferring knowledge from such huge data.
Read MoreUse roc curves to assess classification models.Roc curves plot the true positive rate vs.The false positive rate for different values of a threshold.This video walks through several examples that illustrate broadly what roc curves are and why youd use them.
Read MoreHypothesis testing t-statistic and p-value.The p value and t statistic measure how strong is the evidence that there is a non-zero association.Even a weak effect can be extremely significant given enough data.
Read MoreBy subhan nadeem how bitcoin mining really works as bitcoin approaches mainstream adoption and recognition, its fundamental security model, characterized as mining, is being put under the spotlight and scrutinized more and more everyday.False otherwise.The formula to calculate the new target, run every 20160 minutes two weeks by.
Read MoreEvaluation of clustering typical objective functions in clustering formalize the goal of attaining high intra-cluster similarity documents within a cluster are similar and low inter-cluster similarity documents from different clusters are dissimilar.This is an internal criterion for the quality of a clustering.But good scores on an.
Read MoreOthers provide estimate calculators for clients to use on their websites, fueling wild dreams of fully-funded college education and trips to vegas.Lets dive deeper into that calculator and see how attorneys reach those numbers.The personal injury calculator.The calculator is an easy way to get a ballpark estimate of what your case is worth.
Read MoreSince v0.21, if input is filename or file, the data is first read from the file and then passed to the given callable analyzer.Stopwords str english, list, or none defaultnone.If a string, it is passed to checkstoplist and the appropriate stop list is returned.English.
Read MoreA confusion matrix kohavi and provost, 1998 contains information about actual and predicted classifications done by a classification system.Performance of such systems is commonly evaluated using the data in the matrix.The following table shows the confusion matrix for a two class classifier.
Read MoreHow to calculate the actual size of a table i was looking at one of your previous listing about vsize and that may be one way of doing column by column but if there is.
Read MoreHow to calculate a confusion matrix.Here, is step by step process for calculating a confusion matrix in data mining.Step 1 first, you need to test dataset with its expected outcome values.Step 2 predict all the rows in the test dataset.Step 3 calculate the expected predictions and outcomes the total of correct predictions of each class.
Read MoreHow to calculate a pl.Learn more earnings before interest, taxes, depreciation and amortization -- or ebitda -- is a measure of a companys financial performance.Its not a metric thats defined in generally accepted accounting principles, but it is commonly used by managers, investors and creditors.
Read MoreThe example data for the two-sample ttest shows that the average height in the 2 p.M.Section of biological data analysis was 66.6 inches and the average height in the 5 p.M.Section was 64.6 inches, but the difference is not significant p0.207.You want to know how many students youd have to sample to have an 80 chance of a difference this large being significant.
Read MoreA common problem with pipes is corrosion.Over time, corrosion in a pipe can make a hole that causes a leak.Calculating the fluid flow through a hole can be difficult, due to many variables like fluid flow velocity, pressure in the pipe and density of the fluid, just to name a few, but dont get discouraged.
Read MoreDecision tree - classification decision tree builds classification or regression models in the form of a tree structure.It breaks down a dataset into smaller and smaller subsets while at the same time an associated decision tree is incrementally developed.The final result is a tree with decision nodes and leaf nodes.A decision node e.G.
Read MoreThe following numerology chart can be used in interpreting numbers by considering both their symbolic and literal meanings throughout history.The interpretations presented here are basic and typical and it is important to remember that each number may hold its own interpretation of the individual as all are unique and it is up to each person.
Read MoreThe scatter plot along with the smoothing line above suggests a linearly increasing relationship between the dist and speed variables.This is a good thing, because, one of the underlying assumptions in linear regression is that the relationship between the response and predictor variables is linear and additive.
