Kolmogorov-Smirnov in R vs. SAS statistics - reddit
That worked fine, I have tried it earlier. The thing is I wanted to apply ks.test simultaneously on both the results. See if you help me out, as I am new to r.... Details. These functions perform a goodness-of-fit test of a Poisson point process model fitted to point pattern data. The observed distribution of the values of a spatial covariate at the data points, and the predicted distribution of the same values under the model, are compared using …
Anderson-Darling Ryan-Joiner or Kolmogorov-Smirnov
I'm assuming now that ks.test will consider my data in cumulative form (makes sense now that I think about it, but I didn't want to assume any steps that the R version of k-s test takes). I plan to explore the ideas and run the simulations you sent in full over the weekend.... Details. If y is numeric, a two-sample test of the null hypothesis that x and y were drawn from the same continuous distribution is performed. Alternatively, y can be a character string naming a continuous (cumulative) distribution function (or such a function), or an ecdf function (or object of class stepfun) giving a discrete distribution.

R throws a warning, and you can read ks.test code to learn what it is doing. EDIT: To clarify, data from continuous distributions should not have ties. The R documentation discusses this.

How To Use Ks.test R
It is common to use a Ljung-Box test to check that the residuals from a time series model resemble white noise. However, there is very little practical advice around about how to choose the number of lags for the test. The Ljung-Box test was proposed by Ljung and Box (Biometrika, 1978) and is based on the statistic where is the length of the
- We are finally ready to code the Clauset et al. method to fit the tail of an observed sample to a power law model: # Fits an observed distribution with respect to a Pareto model and computes p value # using method described in: # A. Clauset, C. R. Shalizi, M. E. J. Newman.
- The Kolmogorov-Smirnoff (KS) test was first introduced by Kolmogorov (1933, 1941) and Smirnoff (1939) as a test of the distance or deviation of empirical distributions from a postulated theoretical distribution.

- In R the test is perhaps confusingly called the Wilcoxon test and can be applied to two samples or paired data. The first stage is to arrange your data in a .CSV file . Use a column for each variable and give it a meaningful name.
