Just as the random forest algorithm may be applied to regression and classification tasks, it can also be extended to survival analysis. In the example below a survival model is fit and used for prediction, scoring, and performance analysis using the package randomForestSRC from CRAN. require(rand...

survival is the most commonly used package for survival analysis in R. Using the built-in lung dataset we can get started with Survival Analysis by fitting a regression model with the survreg() function, creating a curve with survfit(), and plotting predicted survival curves by calling the predict m...

zo opens a fold underneath the cursor. zO opens all folds underneath the cursor, recursively. zc closes a fold underneath the cursor. zC closes all folds underneath the cursor, recursively. za toggles a fold under the cursor (a closed fold is opened, an opened fold is closed). zM closes all f...

Applying css intuitively doesn't produce the desired results because vertical-align:middle isn't applicable to block-level elements margin-top:auto and margin-bottom:auto used values would compute as zero margin-top:-50% percentage-based margin values are calculated relative to the width of ...

The diamond problem, or multiple inheritance, is handled by Scala using Traits, which are similar to Java interfaces. Traits are more flexible than interfaces and can include implemented methods. This makes traits similar to mixins in other languages. Scala does not support inheritance from multipl...

Functions allow you to specify these types of parameters: positional, named, variable positional, Keyword args (kwargs). Here is a clear and concise use of each type. def unpacking(a, b, c=45, d=60, *args, **kwargs): print(a, b, c, d, args, kwargs) >>> unpacking(1, 2) 1 2 45 60 ()...

By overloading the indexer you can create a class that looks and feels like an array but isn't. It will have O(1) get and set methods, can access an element at index 100, and yet still have the size of the elements inside of it. The SparseArray class class SparseArray { Dictionary<...

For this example, we will use the vector: > x <- 11:20 > x [1] 11 12 13 14 15 16 17 18 19 20 R vectors are 1-indexed, so for example x[1] will return 11. We can also extract a sub-vector of x by passing a vector of indices to the bracket operator: > x[c(2,4,6)] [1] 12 14 16 ...

By default List.sort sorts in ascending order, with the compare function. There are two ways to sort in descending order: one efficient and one inefficient. The efficient way: List.sortWith and a descending comparison function. descending a b = case compare a b of LT -> GT ...

Conditions are a fundamental part of almost any part of code. They are used to execute some parts of the code only in some situations, but not other. Let's look at the basic syntax: a = 5; if a > 10 % this condition is not fulfilled, so nothing will happen disp('OK') end if a < 1...

In some cases we want to run an alternative code if the condition is false, for this we use the optional else part: a = 20; if a < 10 disp('a smaller than 10') else disp('a bigger than 10') end Here we see that because a is not smaller than 10 the second part of the code, after t...

C++14 Those following duration user literals are declared in the namespace std::literals::chrono_literals, where both literals and chrono_literals are inline namespaces. Access to these operators can be gained with using namespace std::literals, using namespace std::chrono_literals, and using names...
