1. ### Calculating Conditional Probability of Survival

Hi Kat, For example, if none of today's six winning numbers are drawn in the next draw and then none of the following group of six winning numbers are drawn in the next draw, then what is the probability of the third group of winning numbers having one hit in the following draw. So essentially...
2. ### Calculating Conditional Probability of Survival

It would be any one of the six numbers. I had thought of cox regression but it didn't seem like the correct scenario although i'm happy to be proved wrong
3. ### Calculating Conditional Probability of Survival

I’m looking to analyse a Survival data event relating to lottery draw data. The event being is the time taken for one of the six winning numbers to be drawn again. A table of the data is shown as attached I’d be looking to say, find the conditional probability of this event happening in the next...
4. ### Regression with Time Series data

I have count data, some of which forms an exponential decay type distribution and other data sets which are log normal. They are time series and I’m looking to create autoregressive models using first or second order lags. I have a couple of questions which are follows Is normalising the...
5. ### Regression for Exponential Distribution

Hi, I have a set of values which are a time series and follow a decreasing exponential distribution. I would like to understand what the best method might be to predict the next value in the series. Do the options include 1. Transforming the variable to try and get normality. 2. Creating an...
