In the Parameters: Linear regression dialog box, check the box labeledStandard Curve X from Y, because we want our unknown concentrations to be provided. In theOutputoptions category, select theAutooptions for determining where Prism will start and end the regression line. Set the number of s...
The learning curve has a formula to identify a target cumulative average time per unit or batch. The formula for the learning curve is: Y=aXbwhere:Y=Cumulative average time per unit or batcha=Time taken to produce initial quantityX=The cumulative units of production or thecumulative number of...
A graph that represents the density function of the Normal probability distribution is also known as a Normal Curve or a Bell Curve (see Figure 1 below). The Normal distribution requires two parameters, the mean and the standard deviation. A Normal distribution with a mean of zero and a stan...
2. Hopefully a scatter plot will now be displayed. We next need to create a line of best fit through each of the points in the graph to create the standard curve. For this example I will add a linear line to the graph, however, this doesn’t always have to be linear. To do this...

RNA from serum, tissues, or cells was extracted with the TRIzol reagent (Thermo Fisher #15596018). Viral or host RNA levels were determined using the TaqPath™ 1-Step RT-qPCR Master Mix (Thermo Fisher # A15299) on CFX Connect Real-Time System (Bio-Rad) instrument. A standard curve was...
The shape follows a Gompertz curve defined as implied by (1 − exp(−bO)), in which O represents the number of sea otters and b represents an estimated parameter. The line and ribbon indicate the median and 95% credible interval. Extended Data Fig. 8 Posterior parameter distributions...
