WebJun 27, 2009 · I recieve NaN's in the ANOVA table when I try to analyze my unbalanced data using the Statistics Toolbox. I have tried various configurations of data but my results are always NaN's. For example, if I have some unbalanced data (the problem can also occur with balanced data) and code snippet:

WebNULL means that there is no value, while NA and NaN mean that there is some value, although one that is perhaps not usable. Here’s an illustration of the difference: In the first case, it checks if y is NULL, and the answer is no. In the second case, it tries to check if x is `NA, but there is no value to be checked. WebI am using scipy in Python and the following return a nan value for whatever reason: >>>stats.ttest_ind([1, 1], [1, 1]) Ttest_indResult(statistic=nan, pvalue=nan) >>>stats.ttest_ind([1, 1], [1, 1, 1]) Ttest_indResult(statistic=nan, pvalue=nan). But whenever I use samples that have different summary statistics, I actually get a reasonable value: p2psearch免安装
Confidence Interval: getting "NA" as an answer. Why?
WebThe function logL_arch computes an ARCH specification’s (log) likelihood with \(p\) lags. The function returns the negative log-likelihood because most optimization procedures in R are designed to search for minima instead of maximization.. The following lines show how to estimate the model for the time series of demeaned APPL returns (in percent) with … WebJun 17, 2024 · Example 1: Calculate Mean of Vector. The following code shows how to calculate the mean value of a vector in R: #define vector x <- c (3, 6, 7, 7, 12, 14, 19, 22, 24) #calculate mean of vector mean (x) [1] 12.66667. If your vector has missing values, be sure to specify na.rm = TRUE to ignore missing values when calculating the mean: WebMar 21, 2024 · Try running this with both “NA” and “NaN”. You’ll see that it returns a value of TRUE for “NaN” but FALSE for “NA”. The is.na function on the other hand is more generic, so it will detect both types of missing values.
