Of course not. psnr is a measure of how close two images are to each other, not an overall assessment of which image is "better".

It doesn't help to report a P value unless you clearly state what test was used to compute it. Asterisks? Many people add asterisks to tables and graphs to show how low the P value is. The standards for one to three asterisks are quite standard (<0.05, <0.01, <0.001), and both th...

confident that you know what that true proportion is. These confidence interval techniques can be applied to find the exact confidence interval of a mean in R, calculate confidence interval from a p value, or even compute an exact confidence interval for variance in R from a sampling ...
Auto-compute p-value label positions using the functionadd_xy_position()[in rstatix package]. Add the p-values to the plot using the functionstat_pvalue_manual()[in ggpubr package]. The following key options are illustrated in some of the examples: ...

While the mathematics behind these models can be complex, investors don't need to do the calculations manually. Many trading platforms and online tools can quickly compute option prices based on them. While theBlack-Scholesmodel remains the foundation of options pricing, there's a trend toward ev...
Understanding Enterprise Value (EV) Simply put, EV is the sum of a company's market cap and itsnet debt. To compute the EV, total debt—both short- and long-term—is added to a company's market cap, and then cash and cash equivalents are subtracted. ...
