r - How to find log likelihood of Gamma, Log normal and Weibull? -


I want to discover the possibility of logs of normal distributions in Gamma, Weibull and R. Have I already predicted related distribution parameters?

Here's an example for gamma, the webul and log-normal follow the same process. 

  set.seed (101) x

Fitster A log-probability accessor Method: 

  Logic (FF) ## 'Log Leak.' -13.14535 (DF = 2)

Or you can do it by hand: 

  sum (dgamma (x, shape = coef (ff) [ "# 1 [1] -13.14535

Or a little sugar / R-magic: rate = COF (" F "), log = true) 

  (as.list (coef (ff)), sum (dgamma (x, shape = shape, rate = rate, log = TRUE)))

Other distributions

  • -> dweibull ()
  • -> dlnorm ()

In both cases the parameterizes / between the parameters between the match fitdistr and Related Density Functions.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket? SupportForm supportForm: form [supportTicket] = form (mapping ("question" -> text, "priority" -> text) (apply support ticket. (HelpText.update) What are the good practices here? What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....
