### Fit a continuous distribution to a set of discretized probabilities [closed]

I have a probability distribution in the form of discretized bins where the bin value is a lower bound and the upper bound is the value of the succeeding bin. For each bin a probability is assigned so ...

### How to assess model fit with binomial flm?

I have a binomial GLM: site.fit = glm(Presence/Total~Site, family = binomial, weights = Total, data = site.dt) -this looks at how the proportion of data (of the total) which meets the 'present' value (...

### Is it correct to compare two groups' delta G square to approximate an interaction effect?

My experimental design was Group (A vs. B) x Time (1 vs. 2). For group A, from time 1 to 2, ΔG2(1) = 3.97, p=.046 For group B, from time 1 to 2, ΔG2(1) = 1.16, p=.281 Is it correct to calculate a ...

### Measuring goodness of fit/is chi-squared appropriate?

I'm a physics rather than statistics student so please bear with me... I've got a simulation which produces some deterministic curves of the area covered by a particular weather system over time. ...

### what is a good measure of goodness of fit for survival models that can be used for comparison between models?

I don't see any of such measure in the output from coxph() in R (Cox proportional Hazard model). Is there a goodness of fit measure for survival models similar to R2 for linear regression? Update: ...

### Test goodness of fit of a multivariate distribution via testing GOF of linear combinations of components

I am modeling a continuous bivariate distribution of a random vector $(X_1,X_2)$ using a copula. I would like to assess how well I am doing. Given a data sample, I could probably do a bivariate ...

### Calculating the sample cumulative distribution function for a Kolmogrov-Simulation test to examine the goodness of fit with given data [duplicate]

I have sample data for 'Times between successive crashes of a computer system' which is for a 6 month period and the data is given in hours. The data in brief is : 1,10,20,30,40,52..... I need to use ...
